Electrical Simulation of Organic Solar Cell at Different Charge Carrier Mobility

Abstract

The organic photovoltaic device has been electrically simulated by GPVDM software model at different charge carrier mobility. Organic bulk heterojunction solar cell consists of the mixture of electron donor (P3HT) and electron acceptor (PCBM) materials as active layer, ITO (indium tin oxide) is a transparent electrode, PEDOT: PSS is electron blocking layer and Al is a back electrode. In this study the electrical simulation has been done at different charge mobility 0.5 10-4 m 2 v-1 s-1 , 0.5 10-5 m 2 v-1 s-1 , 0.5 10-6 m 2 v-1 s-1 and 0.5 10-7 m 2 v-1 s-1 respectively. It is observed that J-V characteristics are affected by charge carrier mobility and it is concluded that the best J-V characteristic is obtained at 0.5 10-6 m 2 v-1 s-1 carrier mobility.
