Optical Simulation of Different Photoactive Layer Thickness on Organic Solar Cell

2020 
This paper investigated the effect of different layer thickness on the performance of an organic solar cell. Thus, the optical simulations have been performed on organic solar cells based on ITO/PEDOT: PSS/P3HT: PCBM/Al with GPVDM (General-Purpose Photovoltaic Device Model) software 4.8 version 2012. The Optical simulation has been performed with a different photoactive layer thickness of 150nm, 170nm, 200nm, 220nm, 230nm, 250nm, and 300nm at 355-628nm wavelength. The results show that the active layer thickness affects the Photon Absorption Density as well as Power Conversion Efficiency and the best photon absorption is achieved at 200nm.
