Abstract Numerous double perovskites have demonstrated their astonishing potential in several optoelectronic and optical communication areas. Cs2SnI6 has also attracted attention because of its unique vacancy-ordered structure. However, Cs2SnI6 fitted them as good absorbing material still we have attempted to dope Kr atom at the vacancy site to intensify absorption. Herein, we have enumerated the structural, electronic, optical, mechanical and thermoelectric properties of Cs2SnI6 and Cs2SnKrI6. All these physical properties have been computed using density functional theory based Wien2K simulation code. Cs2SnKrI6 exhibits the indirect band gap of ∼ 1.36 eV and direct band gap of ∼ 1.37 eV. Cs2SnI6 and Cs2SnKrI6 both are optically active in visible and near-infrared regions with high absorption. The optical conductivity and power factor are also increased to a substantial level after doping. We have studied the elastic properties to examine the mechanical stability of these materials. We have found B/G ratio of 2.64 and 2.07 for Cs2SnI6 and Cs2SnKrI6 respectively, which demonstrates the ductile nature. After getting these constructive results, we have concluded that power conversion efficiency will also stimulate up to a great extent by doping.

Human welfare depends greatly on electricity, which also has a major impact on a nation’s economic growth. Researchers are focusing on enhancing power availability, quality, and dependability in response to electricity concerns. To resolve the issue of energy lack, this mission has raised the expectation to incorporate environmentally friendly power (RE) into power organizations. However, intermittent sources of RE supply and variable shifts in demand over time have created a high risk for sustaining system dependability in terms of giving consumers an appropriate supply. While not another source of electricity, an energy storage system (ESS) has been shown to be efficient and practical in addressing the aforementioned problems. The evolution of ESS technologies is thus thoroughly reviewed in this study, along with the advantages and practical uses of these technologies. To better comprehend this study, the idea of reliability in power systems is also studied.

The design and development of a hybrid power generating system for rural electrification, as well as the simplicity of monitoring all power generation from individual units and load monitoring utilising IoT, are the main topics of this article. In order to lessen reliance on the grid, the entire hardware system is powered by employing solar PV and wind systems. This project has a number of features, including dualaxis solar panel rotation, Wi-Fi-based remote control monitoring, temperature, humidity, and inverter sensing. Utilizing generated power for rural electrification at any remote locations is the main benefit of HRES. The technology is straightforward: a wind turbine converts mechanical energy into electrical energy, producing output voltage, which is then converted from AC to DC by an AC to DC converter or rectifier. This hybrid power generation system can be used as a grid-connected unit or rooftop self-power generation unit Solar panels and a wind turbine are used in the project. Where solar PV cells are used to harvest solar energy, heat radiation energises the solar cells, causing a chemical reaction that result in the generation of a unit of charge. The usage of an inverter is a cutting-edge technology that converts a DC supply to an AC source. Electrical appliances receive this AC’s supply. Depending on the load and demand requirements, many configurations can be used to obtain the O/p.

Here in, we present the extensive analysis of the parameters associated with structural, electronic, optical and mechanical properties of HC(NH2)2PbI3 or FAPbI3 (FA = Formamidinium) by using full potential linearized augmented plane wave method (FP-LAPW) within framework on the density functional theory. The band structure shows that FAPbI3 has a direct band gap (1.44 eV) at the symmetry point R (0.5, 0.5, 0.5) and are in best agreement with experimental data. The strong hybridization of s orbitals of Pb and p orbitals of I in valance band plays an important role in the structural stability. From the mechanical constants, we have observed that this is ductile in nature and perfect use for photovoltaic applications. Further, FAPbI3 photovoltaic device has been prepared and device parameters have discussed for ZnO, ZnS, ZnSe, ZnTe and CdS buffer layers. The calculated results for FAPbI3 thin layer solar cell show maximum efficiency (20.48% and 20.77%) with ZnS and CdS buffer layers respectively. The proposed results further validate the prospects of methylammonium (MA) free perovskites and it would be persistent and consistent with the flexible substratum. These are the main features of commercialization perovskite solar cells. Thus, promoting the evolution of cubic FAPbI3, for achieving high performance-based optoelectronic devices and will pave a new path in solar cell industry.
