Characteristic Features and Performance Investigations of a PTB7:PC71BM/PFN:Br Pure Organic Solar Cell Using SCAPS-1D

Organic solar cells are becoming a point of interest for researchers because they are less polluting than available solar cells in the photovoltaics industry. In this present work, we have optimized the characteristic parameters of the PTB7:PC71BM active layer along with graphene oxide (GO) as the hole transport layer (HTL) and PFN:Br as an electron transport layer (ETL) in the proposed organic solar cell. By optimizing the electron affinity ( χ Active ) of the active layer, we observed the highest cell power conversion efficiency (PCE) of about 15.31
