Investigation on Effect of Thickness Variation of Active Layer in Organic Solar Cell and Analysis of Fill Factor and Power Conversion Efficiency

In recent years, research into low-cost Organic Solar Cell (OSC) technology has gained popularity. The usage of OSC and its numerous advantages has helped to accelerate the shift from crystalline to organic solar cells. The purpose of this research work is to estimate the highest power conversion efficiency of the PM6_D18_L8-BO organic solar cell by modifying its active layer thickness using GPVDM software. The impact of various active layer thicknesses on the efficiency of organic photovoltaics has been studied. The electrical and optical characteristics of OSCs based on ITO/PEDOT:PSS/PM6_D18_L8-BO/PNDIT-F3N/Ag were simulated using the General-Purpose Photovoltaic Device Model. The optimum power conversion efficiency is 17.876%.
