A variety of solar systems can include hybrid halide perovskites. These types of perovskites have lower toxicity, more structural stability and show improvement in the bandgap as compared to ethyl ammonium-based hybrid perovskites. The structural, electrical, optical and thermoelectric properties of Ethyl ammonium Tin Bromide have been evaluated with the help of the software density functional theory (DFT), in particular WIEN2K simulation code. The use of the exchange-correlation potential KTB-mBJ makes it possible to determine the optimized structure, density of states, and band structure of EASnBr3 which is quite evidently a semiconductor material that has a direct bandgap and a very high absorption coefficient in the Ultraviolet to Visible range. These findings help to tackle the environmental issues as it makes sure that it is an appropriate and cheap material to be used in solar panels.

摘要

A variety of solar systems can include hybrid halide perovskites. These types of perovskites have lower toxicity, more structural stability and show improvement in the bandgap as compared to ethyl ammonium-based hybrid perovskites. The structural, electrical, optical and thermoelectric properties of Ethyl ammonium Tin Bromide have been evaluated with the help of the software density functional theory (DFT), in particular WIEN2K simulation code. The use of the exchange-correlation potential KTB-mBJ makes it possible to determine the optimized structure, density of states, and band structure of EASnBr3 which is quite evidently a semiconductor material that has a direct bandgap and a very high absorption coefficient in the Ultraviolet to Visible range. These findings help to tackle the environmental issues as it makes sure that it is an appropriate and cheap material to be used in solar panels.
