Opto-Electro Simulation of Organic Solar Cell at Different Active Layer Thickness and Charge Carriers Mobility Based on P3HT: PCBM Materials

Abstract

In this research work, bulk heterojunction organic solar cell is simulated optically and electrically at different active layer thickness and different hole mobility by General-purpose Photovoltaic Device Model (GPVDM) software. Organic bulk heterojunction solar cell consists of mixture of poly (3-hexylthiophene) (P3HT) and [Rait, S. et al., 2007]-phenyl C61-butyric acid methylester (PCBM) as active layer material, Indium Tin oxide (ITO) is a transparent electrode, Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) is an electron blocking layer and Al a back electrode. In this work, the optical reproduction has been done at various dynamic layer thicknesses for example 180 nm, 200 nm and 220 nm, and electrical reproduction at various opening portability 1×10-4cm2/Vs, 1×10-5cm2/Vs, 1×10-6cm2/Vs and 1×10-7cm2/Vs individually. It is seen that current-voltage (j-v) attributes are impacted by the opening portability. The best current-voltage (j-v) trademark is acquired at 1×10-6cm2/Vs versatility and the best ingestion at 200 nm. It is inferred that in the natural BHJ sunlight based cell the effectiveness increments, when versatility diminishes (from 10-4 to 10-6) where as over 10-7 portability, the productivity further abatements. On the off chance that the versatility is expanded from 1×10-5cm2/Vs the separation likelihood is expanded and will be greatest at 1×10-6cm2/Vs, and again increment the portability the separation won’t further increment and effectiveness is decline
