Fullerene-C 60 and PCBM as interlayers in regular and inverted lead-free PSCs using CH 3 NH 3 SnI 3 : an analysis of device performance and defect density dependence by SCAPS-1D

The use of fullerene-C 60 and PCBM as interlayers in lead-free PSCs can positively impact the optimized parameters of these solar cells. The simulation program SCAPS-1D was used to simulate inverted and regular PSCs using interlayers in MASI PSCs.
