Organic solar cells (OSCs) have the potential to generate electricity under sunlight at a low cost. In this study, the influence of active layer thickness, defect density, temperature and the presence of reflective coating is studied for the structure ITO/PTAA/PBDB-T: ITIC-OE/PDINO/Ag, by applying PTAA as a hole transport layer (HTL), while the blend of PBDB-T: ITIC-OE is used as an active layer and PDINO is applied as electron transport layer (ETL), respectively. Solar capacitance simulator one-dimensional (SCAPS—1D) software is used to optimize different parameters, which affect the performance of OSCs. By introducing backside reflective coating, the efficiency increases by 2.5%. In the future, this study can be used for the power conversion efficiency (PCE) enhancement of OSCs.
