Unveiling the Role of Donor Polymer Antisolvent Additives in the Enhanced Performance and Stability of Carbon-Based Perovskite Solar Cells Setiyadi Tri Utomo, Widhya Budiawan, Imam Ali Firdaus, Cristian Rosero-Arias, Sudirman Sudirman, Mohamad Insan Nugraha, Asmida Herawati, Abdulrahman El Labban, Phutri Milana, Risa Suryana, Veinardi Suendo, Han J.G.E. Gardeniers, Arturo Susarrey-Arce, Ferry Anggoro Ardy Nugroho, Yuliar Firdaus ACS Applied Energy Materials, 2026 Low-temperature, solution-processed carbon-based perovskite solar cells (c-PSCs) often suffer from surface defects and nonideal crystallization caused by rapid antisolvent quenching of MAPbI 3 . To this end, incorporating polymers as antisolvent additives offers a simple route to regulate crystallization and reduce interfacial defects. Here, four donor polymers─P3HT, PCE10, PM6, and PM7─are introduced during MAPbI 3 deposition. Their distinct Highest Occupied Molecular Orbital (HOMO) energy levels enable us to probe how energetic alignment influences their interaction with MAPbI 3 surfaces and their passivation capability. The additives are found to improve crystallinity, yielding larger grains and lower trap densities. In particular, PM7 provides the highest enhancements because its HOMO level lies closest to the MAPbI 3 valence band, enabling more favorable interfacial passivation and more effective suppression of surface recombination. Consequently, PM7-treated films exhibit longer photocarrier lifetimes, lower ideality factors, reduced interfacial resistance, and smaller trap-filled limit voltages. Devices using PM7 reach a PCE of 14.6%, a 53.8% improvement over the control. Overall, this study demonstrates that the HOMO level of antisolvent additives is a decisive factor governing interfacial interactions and enhancing MAPbI 3 passivation.
n-Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz Lazaros Panagiotidis, Filip Aniés, Yiyang Yu, Mohammed Ghadiyali, Hendrik Faber, Zhanibek Bizak, Youssef Kabri, Pavlos Tzourmpakis, Suman Mandal, Linqu Luo, Temur Maksudov, Mohamad Insan Nugraha, Harold F. Mazo‐Mantilla, Patrice Vanelle, Julie Broggi, Khaled N. Salama, Udo Schwingenschlögl, Martin Heeney, Atif Shamim, Thomas D. Anthopoulos Advanced Materials, 2026 As advancements in artificial intelligence, the Internet of Things (IoT), and telecommunication technologies continue to accelerate, the demand for cheaper radiofrequency (RF) electronics increases. However, developing devices that meet the stringent manufacturing and performance criteria for RF applications remains a significant challenge. Here, we demonstrate organic polymeric RF Schottky diodes and rectifier circuits that can operate up to 18.5 GHz, making them the fastest organic devices reported to date. The diodes feature the molecularly n‐doped polymer, namely N2200, deposited atop self‐aligned coplanar asymmetric nanogap electrodes (sub‐20‐nm nanogaps). The coplanar architecture reduces parasitic capacitances, while the engineered electron‐injecting contacts, in synergy with the n‐doped polymer, help decrease the contact resistance and boost the device's overall performance. The polymer Schottky diodes exhibit a low turn‐on voltage of ≈0.15 V, a high current rectification ratio exceeding 10 5 , and an ultra‐low capacitance of ≈2 pF. RF rectifier circuits featuring the polymer Schottky diodes yield a maximum output voltage ( V PEAK ) of 1.43 V and an extrinsic cut‐off frequency of up to 18.5 GHz. The scalable manufacturing and unprecedented frequency response make these organic Schottky diodes a good candidate for applications in emerging RF electronics for wearables and the broader IoT device ecosystem.
Three-dimensional integrated hybrid complementary circuits for large-area electronics Saravanan Yuvaraja, Mohamad Insan Nugraha, Qiao He, Leo Raj Solay, Patsy Arely Miranda Cortez, Na Xiao, Martin Heeney, Thomas D. Anthopoulos, Xiaohang Li Nature Electronics, 2025 The development of low-power computing sectors requires compact, power-efficient and high-performance integrated circuits. Hybrid technology that combines n-type metal oxide thin-film transistors and p-type organic thin-film transistors offers a potential solution. However, increasing the transistor density of these systems through vertical stacking is challenging due to issues related to thermal budget and interface roughness. Here we report a six-stack hybrid complementary transistor technology that has 41 layers and uses n-type indium oxide (In 2 O 3 ) and a p-type organic semiconductor (C16IDT-BT) as channel materials. We test 600 transistors and show that n-type oxide devices and p-type organic devices exhibit comparable field-effect mobilities and saturation currents. We also create 300 hybrid inverters by integrating the oxide and organic transistors; the circuits exhibit a gain of 94.84 V V −1 and a power consumption of 0.47 µW. We also fabricate NAND and NOR gates comprising transistors from four stacks. Thermal stability analysis shows that device characteristics begin to degrade above 50 °C, a known limitation of low-thermal-budget processes. Such performance is sufficient for many large-area electronics applications, but further thermal optimization will be necessary to extend operational robustness towards standard industrial conditions.
Concurrent Interface Passivation and Contact Work Function Tuning in Organic Self-Aligned Gate Transistors and Complementary Circuits Using Phosphonic Acid Self-Assembled Monolayers Linqu Luo, Mohamad Insan Nugraha, Hendrik Faber, Shaoxian Li, Chrysa Aivalioti, Bahaaeddin Irziqat, Ricardo Ruvalcaba, Temur Maksudov, Yu‐ying Yang, Harold F. MazoMantilla, Lazaros Panagiotidis, Mohamed Nejib Hedhili, Furkan H. Isikgor, Leonidas Tsetseris, Shadi Fatayer, Martin Heeney, Thomas D. Anthopoulos Advanced Functional Materials, 2025 The self‐aligned gate (SAG) transistor architecture is attractive for electronic circuit applications due to its enabling attributes, including low parasitic capacitances and higher frequency operation. However, SAG transistors often rely on complex manufacturing, which limits their practical utilization. Herein, we overcome this bottleneck and demonstrate organic SAG transistors in which the self‐aligned source/drain (S/D) electrodes are separated by the gate (G) terminal with sub‐20 nm gaps. The SAG architecture eliminates parasitic overlaps while minimizing access resistance for the injected carriers. Moreover, precise work function engineering of the self‐aligned Au S/D contacts is demonstrated using phosphonic acid (PA) self‐assembled monolayers (SAMs) functionalized directly onto Au. Analysis of the Au surface corroborated by Density Functional Theory calculations and scanning tunneling microscopy reveal the unexpected formation of PA SAMs directly onto Au for the first time. Combining different organic semiconductors with appropriate SAMs enables the development of hole and electron‐transporting SAG transistors with enhanced performance. Integrating the n‐ and p‐channel transistors yields complementary logic circuitry with high gain and noise margins, showcasing the effectiveness of this approach. The work highlights the enormous potential of combining the SAG transistor platform with work function modifying PA SAMs to develop printed electronics with improved functionality.
Preparation of Thermally and Photochemically Immobilized N-type Conjugated Polymer Films via Quantitative Backbone Editing Charlotte Rapley, Adam V. Marsh, Edgar Gutierrez‐Fernandez, Mohamad Insan Nugraha, Flurin Eisner, Martina Rimmele, Jaime Martín, Thomas D. Anthopoulos, Martin Heeney Angewandte Chemie International Edition, 2025 We report a series of n‐type conjugated polymers based on PNDI‐TfBTT and PNDIV‐TfBTT backbones constructed from electron‐deficient naphthalene diimide (NDI) and fluorinated benzothiadiazole (fBT) units, with PNDIV‐TfBTT incorporating a vinylene spacer. Quantitative postpolymerization modification (PPM) via nucleophilic substitution replaced the fBT fluorine with thioether side chains, optionally containing azide groups. Thioether substitution improved solubility, while subtly changing the ordering of polymer films. Azide incorporation enabled both thermal and photochemical crosslinking, yielding insoluble and immobile films that retained good electron transport; although UV crosslinking initially reduced mobility, subsequent thermal annealing largely restored crystallinity and performance. This work underscores the utility of precise backbone editing to fine‐tune the electronic and morphological properties of n‐type polymers, offering new avenues for the fabrication of stable, patterned active layers in advanced organic electronic devices.
Selective Tuning of Benzothiadiazole Functionality Enables High Crystallinity and Mobility in Regiorandom n-Type Polymers for Organic Field-Effect Transistors Panagiota Kafourou, Qiao He, Xiantao Hu, Mohamad Insan Nugraha, Wen Liang Tan, Joel Luke, Bowen Ding, Christopher R. McNeill, Thomas D. Anthopoulos, Martin Heeney Macromolecules, 2025 High Resolution Image Download MS PowerPoint Slide We report three novel donor–acceptor (D–A) copolymers sharing a common fused donor unit (CDTT) but differing in the functionalization of the benzothiadiazole (BT) acceptor unit. Acceptors bearing two cyano groups (DCNBT) are compared to novel acceptors bearing one cyano and one fluorine group (FCNBT) or one nitro and one fluoro group (NO 2 FBT). The choice of the acceptor has a significant effect on the optoelectronic properties of the resulting polymers. In organic field-effect transistor (OFET) devices, PCDTT-DCNBT exhibited moderate performance with an electron mobility of 0.031 cm 2 V –1 s –1, whereas PCDTT-FCNBT demonstrated significantly improved electron mobility (0.4 cm 2 V –1 s –1 ). The improved performance is attributed to increased backbone linearity combined with a more coplanar backbone and high thin-film crystallinity. In comparison, the presence of the nitro group is shown to have a detrimental impact, with a blue-shifted absorption and a 0.2 eV increase in band gap compared to the cyanated polymers. Steric effects are shown to limit the nitro group’s π-accepting capability and result in reduced device performance, with an electron mobility of 0.024 cm 2 V –1 s –1 . This study introduces a new BT building block and highlights that substituent tuning via cyano and fluorine groups is an effective approach for modulating polymer morphology and electron transport.
On-Surface Reactions of Electronically Active Self-Assembled Monolayers for Electrode Work Function Tuning Ricardo Ruvalcaba, Zhongzhe Liu, Mohamad Insan Nugraha, George Harrison, Yu-Ying Yang, Marco Thaler, Adam V. Marsh, Matthias Zeilerbauer, Chrysa Aivalioti, Raul Ricardo Aguileta-Vazquez, Leonidas Tsetseris, Laerte L. Patera, Percy Zahl, Martin Heeney, Thomas D. Anthopoulos, Shadi Fatayer ACS Materials Letters, 2025 High Resolution Image Download MS PowerPoint Slide Self-assembled monolayers (SAMs) help improve the performance of organic electronic devices through interface passivation and enhanced carrier transport. Yet, there is limited information regarding the chemical structure of the SAMs upon functionalization and subsequent thermal treatment. Here, we studied the on-surface reaction of carbazole-derived SAMs on model gold electrodes, focusing on the chemical structure changes induced by thermal treatments. Furthermore, we correlate the microscopic changes with their impact on the electrode’s work function. The carbazole-based SAMs first transform into organometallic complexes. At higher annealing temperatures, SAMs convert to oligomeric complexes. The observed chemical reactions significantly reduce the electrode work function and facilitate electron injection in n-type organic thin-film transistors. Our results highlight the on-surface synthesis of electronically active SAMs as an alternative approach for modifying the work function of electrodes for organic electronics.
20.5 % efficient ternary organic photovoltaics using an asymmetric small-molecular acceptor to manipulate intermolecular packing and reduce energy losses Zhaoheng Ling, Jingnan Wu, José P. Jurado, Christopher E. Petoukhoff, Sang Young Jeong, Dipti Naphade, Maxime Babics, Xiaoming Chang, Hendrik Faber, Spyros Doukas, Elefterios Lidorikis, Mohamad Insan Nugraha, Mingjie He, Maryam Alqurashi, Yuanbao Lin, Xiaokang Sun, Hanlin Hu, Han Young Woo, Stefaan De Wolf, Leonidas Tsetseris, Frédéric Laquai, Donghong Yu, Ergang Wang, Thomas D. Anthopoulos Materials Science and Engineering R Reports, 2025 Oligomeric acceptors are increasingly recognized as promising n-type materials for organic photovoltaics (OPVs) due to their precise molecular structures, long-term stability, and high efficiency. However, inferior molecular packing and high energy losses have hindered their further use. Here, we overcome these challenges by developing an asymmetric small molecular acceptor (SMA), BTP-J17, and applying it as the second acceptor component in OPVs composed of PM6:DIBP3F-Se:BTP-J17 (refer to our recent work on dimeric acceptor DIBP3F-Se). The BTP-J17 is very miscible with the DIBP3F-Se and appears to diffuse into the host donor-acceptor interface. The ensuing ternary cells exhibit enhanced exciton dissociation, improved carrier mobility, and more efficient charge extraction. Optimised OPVs based on PM6:DIBP3F-Se:BTP-J17 show enhanced open-circuit voltage ( V OC ) while maintaining the high short-circuit current ( J SC ) from the binary blends, boosting the power conversion efficiency (PCE) from 18.40 % to 19.60 %. By integrating MgF 2 as an antireflection coating and n-doping the ternary BHJ with ethyl viologen (EV), we were able to further boost the PCE to 20.5 % (uncertified) and simultaneously extended the outdoor stability to seven weeks. Our findings highlight the crucial role of asymmetric SMA as an additional component for boosting the performance and stability of OPVs.
Thiol Carbazole Self-Assembled Monolayers as Tunable Carrier Injecting Interlayers for Organic Transistors and Complementary Circuits Mohamad Insan Nugraha, Yu‐Ying Yang, Zhongzhe Liu, George T. Harrison, Ryanda Enggar Anugrah Ardhi, Yuliar Firdaus, Qiao He, Linqu Luo, Mohamed Nejib Hedhili, Marco Thaler, Zhaoheng Ling, Matthias Zeilerbauer, Laerte L. Patera, Leonidas Tsetseris, Shadi Fatayer, Martin Heeney, Thomas D. Anthopoulos Advanced Materials, 2025 The significant contact resistance at the metal‐semiconductor interface is a well‐documented issue for organic thin‐film transistors (OTFTs) that hinders device and circuit performance. Here, this issue is tackled by developing three new thiol carbazole‐based self‐assembled monolayer (SAM) molecules, namely tBu‐2SCz, 2SCz, and Br‐2SCz, and utilizing them as carrier‐selective injection interlayers. The SAMs alter the work function of gold electrodes by more than 1 eV, making them suitable for use in hole and electron‐transporting OTFTs. Scanning tunneling microscopy analysis indicates that 2SCz and Br‐2SCz form highly ordered molecular rows, resulting in work function values of 4.86 and 5.48 eV, respectively. The latter value is higher than gold electrodes modified by the commonly used pentafluorobenzenethiol (≈5.33 eV), making Br‐2SCz promising for hole injection. Conversely, tBu‐2SCz appears disordered with a lower work function of 4.52 eV, making it more suitable for electron injection. These intriguing properties are leveraged to demonstrate hole‐ and electron‐transporting OTFTs with improved operating characteristics. All‐organic complementary inverters are finally demonstrated by integrating p‐ and n‐channel OTFTs, showcasing the potential of this simple yet powerful contact work function engineering approach. The present study highlights the versatility of thiol carbazole SAMs as carrier injecting interlayers for OTFTs and integrated circuits.
Enhancing the Electrical Conductivity and Long-Term Stability of PEDOT:PSS Electrodes through Sequential Treatment with Nitric Acid and Cesium Chloride Begimai Adilbekova, Alberto D. Scaccabarozzi, Hendrik Faber, Mohamad Insan Nugraha, Vladimir Bruevich, Dimitris Kaltsas, Dipti R. Naphade, Nimer Wehbe, Abdul‐Hamid Emwas, Husam N. Alshareef, Vitaly Podzorov, Jaime Martín, Leonidas Tsetseris, Thomas D. Anthopoulos Advanced Materials, 2024 Solution‐processable poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) is an important polymeric conductor used extensively in organic flexible, wearable, and stretchable optoelectronics. However, further enhancing its conductivity and long‐term stability while maintaining its superb mechanical properties remains challenging. Here, a novel post‐treatment approach to enhance the electrical properties and stability of sub‐20‐nm‐thin PEDOT:PSS films processed from solution is introduced. The approach involves a sequential post‐treatment with HNO3 and CsCl, resulting in a remarkable enhancement of the electrical conductivity of PEDOT:PSS films to over 5500 S cm−1, along with improved carrier mobility. The post‐treated films exhibit remarkable air stability, retaining over 85% of their initial conductivity even after 270 days of storage. Various characterization techniques, including X‐ray photoelectron spectroscopy, atomic force microscopy, Raman spectroscopy, Hall effect measurements, and grazing incidence wide angle X‐ray scattering, coupled with density functional theory calculations, provide insights into the structural changes and interactions responsible for these improvements. To demonstrate the potential for practical applications, the ultrathin PEDOT:PSS films are connected to an inorganic light‐emitting diode with a battery, showcasing their suitability as transparent electrodes. This work presents a promising approach for enhancing the electrical conductivity of PEDOT:PSS while offering a comprehensive understanding of the underlying mechanisms that can guide further advances.
