Comparative Study on Perovskite Solar Cells Using Inorganic Transport Layers

摘要

In this paper, a numerical analysis of organo-halide based planar n-i-p perovskite solar cell (PSC) has been presented using Solar Cell Capacitance Simulator (SCAPS-1D). The performance of the FTO/Ti02/perovskite/CZTS PSC structure has been investigated by varying the thickness of the absorber layer. That the doping density of the absorber layer affects the PSC performance has been investigated using SCAPS simulation. Considering an absorber thickness of 220 nm and absorber doping density of 10¹⁵ cm^-3, the PSC performance is also investigated for various electron/hole transporting materials (ETMs/HTMs). It has been found that the properties of HTM affect the PSC performance more significantly than that of ETM. Finally, it is observed that CZTS based PSC shows better performance than the CIGS based PSC.
