Analysis of Different Layers Thicknesses on the Performance of Organic Solar Cells

An organic Solar cell (OSC) with inverted configuration i.e. “FTO/TiO
2
/P3HT:PCBM/PEDOT:PSS/Ag” has been studied using an open source software OghmaNano. The thicknesses of active layer, electron transport layer (ETL), hole transport layer (HTL), cathode, and anode are varied and the corresponding current-voltage characteristics are obtained. After examining the open-circuit voltage (Voc), short-circuit current density (Jsc), fill-factor (FF), and the power conversion efficiency (PCE), the optimize thicknesses of active layer, ETL, HTL, cathode, and anode are obtained as 200, 40, 40, 10, and 10 nm respectively. A PCE of 5.37% is obtained with the optimized device structure.
