AbstractPerovskite solar cells (PSC) are the third‐generation solar cells, which have a low production cost and have achieved similar laboratory scale efficiencies as the first‐generation silicon solar cells. In the present work, we performed density functional theory calculations on the organic material, poly[3‐(5‐carboxypentyl) thiophene‐2,5‐diyl] regioregular (P3CPenT). The ground state and excited state properties of P3CPenT are calculated. The HOMO‐LUMO levels and electronic bandgap obtained from the calculations are compared with the experimental values for validation of the theory. A high electron reorganization energy and low hole reorganization energy ensures that P3CPenT aids the flow of holes and hinders the flow of electrons. The optical bandgap and low exciton binding energy indicates its potential as a hole transport layer (HTL). The ease of fabrication of P3CPenT is established by showing that the oligomer is soluble in dimethyl sulfoxide (DMSO), which is the most commonly utilized solvent for the fabrication of PSCs. The hydrophobic nature of P3CPenT as established by the present work shows that it is stable with moisture and would thus protect the underlying MAPbI3 perovskite layer from decomposing and hence improve its lifetime and stability. Fill factor (FF) of 78.07% and a power conversion efficiency (PCE) of 14.88% has been obtained for PSC with P3CPenT HTL.

Abstract The membrane separation process lacks intrinsic permeation characteristics to compete with other separation technologies like adsorption, sedimentation, coagulation, skimming, and distillation. A mixed matrix membrane (MMM) is one of the strategies to improve the separation characteristics with embedded nanofillers particles. Zeolite imidazolate framework (ZIF) has a new subclass of inorganic–organic hybrid materials that are being introduced as new fillers for incorporation into the polymer matrix for various applications such as oily wastewater separation, wastewater treatment, natural gas dehydration, landfill gas upgrading, and mixed gas separation. In this experimental work, a metal-organic framework called ZIF-8 was synthesized and used as a filler for modification of MMMs and characterized with FTIR and SEM. ZIF-8 nanoparticles up to 5 wt% loading were added to PSF casting solution then the permeation characteristics of MMMs showed an improved result like the pure water flux of the modified membrane at 2.5 bar was increased up to 456.38 L/m2h. In the case of pure gas separation, at 5 wt% ZIF-8 loading in PSF, the pure gas CO2 permeability at 9 bar pressure had increased to 10.54 barrer.

Abstract The implementation and commercialization of perovskite solar cells (PSCs) are hindered due to the presence of toxic lead. Metal phthalocyanines (MPc) have been studied extensively as charge transport layers (CTLs) in PSCs due to their desirable properties such as thermal and chemical robustness, and low production cost. In the present work, a theoretical study of the effect of phthalocyanine-based CTLs on a non-leaded KSnI3-based PSC is carried out using SCAPS software. The defect concentration of the layers and the interfaces, doping density and thickness of the layers, shunt, and series resistance of the device is optimized. Carbon is suggested as an affordable alternative to the state of art back contact material, gold. The stability of this device with temperature is also established. The optimized solar cell showed an excellent fill factor (FF) of 86.51% with a power conversion efficiency (PCE) of 11.91% and an excellent quantum efficiency (QE) ranging from 99.42%(400 nm) to 72.02%(660 nm) in the visible region. The present study highlights the enhanced performance parameters of leadless KSnI3-based PSC with phthalocyanine-based CTLs as compared to the state-of-art CTLs, TiO2 and Spiro-OMeTAD reported in previous literature with a PCE and FF of 9.776% and 36.139% respectively.

The state‐of‐art charge transport materials, TiO2 and Spiro‐OMeTAD suffer from various drawbacks such as instability, lengthy fabrication procedure and low charge mobilities. In this paper, we have studied copper phthalocyanine (CuPc) and halogen‐substituted copper phthalocyanine (X16CuPc; X = F, Cl, Br, I) through density functional theory (DFT) and determined their ground state properties, excited state properties and solubility in DMSO (widely used solvent in the fabrication of perovskite solar cell [PSC]). We have shown that fluorinated copper phthalocyanine(F16CuPc) acts as an electron transport layer (ETL) and CuPc acts as a hole transport layer (HTL) in MAPbI3‐based PSC. The moisture stability of CuPc and F16CuPc has been established and it has been shown that CuPc and F16CuPc will protect the perovskite layer from degradation due to the presence of moisture in the surroundings. Using the properties obtained via DFT, PSC has been simulated using SCAPS, and it is established that CuPc as hole transport material and F16CuPc as electron transport material gives better efficiency compared with the state of art charge transport materials (TiO2 and Spiro‐OMeTAD). The device has been optimized with respect to (w.r.t.) thickness, doping concentration, defect density and interface defect density. We have studied the effect of series resistance, shunt resistance and temperature on the performance of PSC and this configuration has shown good thermal stability. Carbon has been proposed as an alternative to gold as the back contact thereby making our device more economical. The optimized device showed quantum efficiency of (81.59% to 98.69%) in the visible region. A fill factor of 79.01%, power conversion efficiency of 22.30% has been obtained.

AbstractThe supramolecular complexation of flutamide, an anti‐androgen drug with cucurbit[n]uril was studies using density functional theory (DFT). The structural and electronic analysis of the complexes was performed. The negative binding energy of the complexes show that complexation process is exothermic. The thermodynamic results reveal that the process of inclusion complex formation is spontaneous. To gain insightful knowledge about the nature of interactions present between the host‐guest molecules of the complexes, molecular electrostatic potential, non‐covalent interaction–reduced density gradient, and natural bond orbital analysis was done. These results suggest that electrostatic interactions and intermolecular hydrogen bond formation contribute to the stability of these complexes. The coupled‐cluster theory with single, double and perturbatively connected triple excitations calculations for the complexes support the DFT results. The quantitative decomposition of the interaction energies of the complexes was acquired by the local energy decomposition analysis. The atom‐centered density matrix propagation molecular dynamic analysis confirms the stability of the examined complexes.
