Comparative Simulation-Based Study on Different Active Layers of Organic Solar Cell via GPVDM

Abstract

The high strength of organic photovoltaic cells lies in the variety of organic ingredients that can be built and synthesized for absorbers, receptors, and boundaries. Still, we need further development for better performance and existence of the system. In this research study, electrical simulations of different active layer materials have been performed via GPVDM software to observe the outcomes of a solar cell. Furthermore, the electrical simulation has been performed at different active layer thicknesses from 50 nm to 300 nm with active material P3HT: PC70BM. We analyzed by performing simulations with different parameters to observe the best parameters for organic solar cell performance. We observed that absorber layer thickness of 200 nm, hole transport layer of Cu2O, pair of ITO/Al electrodes, and exponential DOS exhibit superior outcomes. At the same time, the highest power conversion efficiency was reported with active layer PTB7:PCB70BM due to its efficient optical properties. Organic solar cells are versatile and gaining popularity for a broad range of applications to keep up with the increasing energy demand and comparatively lower energy payback time.
