Numerical analysis for thermal stability evaluation of perovskite solar cell using SCAPS-1D

The benefits of third generation hybrid organic-inorganic metal-halide Perovskite Solar cells (PSC), makes it the potential candidate among all solar cells, but challenges on improving stability of the Perovskite solar cell makes it the secondary option compared to the conventional solar cells. In this paper, simulation work on the stability intended combinations of ideal layers such as HTL (CuSCN) / ETL (SnO2) along with the absorber layers CH3NH3MAPb (I 1-xCl x)3, FAPbI3and Rb0.5 Cs0.1 FA 0.85 Pb I3are conceded. Here, the thermal variations are being investigated and the study reveals that as temperature increases from 250K to 450K the efficiency of FAPbI3 based PSC falls from 21.7% to 11.1% andfrom 20.1% to 13.9% for Rb0.5 Cs0.1 FA 0.85 PbI3based PSC and from 20.8% to 14.2% for MAPb(I 1-xCl x)3based PSC. The simulation work also shows that the proposed structure with charge transport layers ETL (SnO2),HTL (CuSCN) and active layer MAPb (I 1-xCl x) 3has the potential for improving thermal stability.
