Abstract:
Recently, methyl ammonium lead triiodide (MAPbI3) perovskite solar cell (PSC) has surpassed the power conversion efficiency (PCE) of most of the established photo voltaic technologies, with PCE of 25.7%. But achieving long term structural stability still remains a hurdle in its large-scale commercialization. The methyl ammonium (MA) in perovskite material has low thermal conductivity and degrades with the built up of heat in it. This causes the leakage of the toxic lead into the environment. Research is being focused on replacing the MA with alternate thermal stable material. One such material is formamadium (FA). Formamadium lead triiodide (FAPbI3) is more thermally and structurally stable than MAPbI3 but has lower efficiency. The performance of the FA-PSC can be enhanced by identifying the optimized design parameters of each layer in the PSC structure. In this work the FAPbI3 is numerically modelled with CBTS and ZnO as charge transport layers in SCAPS-1D. A systematic approach is adopted to identify the optimized design parameters of each layer (hole transport layer, absorber and electron transport layer). After optimization the PCE of 24 % was achieved with Jsc of 24.271454 mA/cm2, Voc of 1.140949 V and fill factor of 86.65 %. Moreover, the effect of varying layer thickness, doping concentration, defect density and working temperature on the performance of FAPbI3 is analyzed in detail
