Abstract
The growing requirement for electricity and its inadequate fossil fuel supply is a global concern that's why organic solar cell (OSC) devices had more attraction in the last decades for their practical application. In this research study, GPVDM software is considered, a 3-D photovoltaic device model, used to observe the outcomes of PTB7: PC70BM based organic solar cell. The organic solar cell comprises a PTB7:PC70BM as an active layer, indium tin oxide (ITO) serving as a transparent conducting oxide, and front electrode, PEDOT: PSS for efficient transporting of holes, while Al is taken as a back metal electrode. The electrical simulation via GPVDM has been performed at different active layer thicknesses and charge carrier mobility. Furthermore, the influence of varying different HTM layers had also been studied. The optimum efficiency of OSC is obtained at 200 nm active layer thickness and carrier mobility of 2.46 x 106 m2/Vs. The outcomes and performance of the simulated organic solar cell are compared with the practically implemented organic solar cell. This research also suggests a possible path toward the efficient implementation of organic solar cells by modifying factors that are significantly reliant on the performance and outcomes of OSCs.
