Photovoltaic Performance of BHJ Organic Solar Cells Based on Incorporation of Ru Dye into P3HT:PCBM Matrix

Abstract

Abstract:In this study, spin coating method was used for fabricating the P3HT:PCBM bulk heterojunction organic photovoltaic (OPV) devices comprising of Ru dye at different concentrations. The effects of Ru dye incorporated into P3HT:PCBM matrix on photovoltaic and diode parameters of the devices were investigated. It was observed that incorporating Ru dye with the lowest concentration into ternary system, improved the device performance, whereas device performance decreased with the increasing concentration of Ru dye in the blend of ternary system. The power conversion efficiency of OPV device was enhanced about 10% with incorporating Ru dye.
