Numerical Optimization of Electron and Hole Selective Layers for PM7:PiDT Bulk-Heterojunctions Solar Cell
摘要
This paper presents a comprehensive analysis of the numerical modeling and evaluation of polymer solar cell designs using PM7:PIDT active layers, which include multiple electron and hole-selective layers. The hole-transport layer (HTL) under consideration comprises the following materials: Cu2O, CuSbS2, CuSCN, P3HT, PEDOT: PSS, and Spiro-OMeTAD. The ETL consists of titanium dioxide (TiO2), fullerene (C60), zinc oxide (ZnO), tin dioxide (SnO2), and phenyl-C61-butyric acid methyl ester (PCBM). The best power conversion efficiency of 20.86% was observed in the Au/CuSbS2/PM7:PIDT/TiO2/ITO heterojunction solar cell.
