Organic solar cells (OSCs) are the most promising alternative sources of energy as they can play an important role in generating clean and cheap energy [1]. The design for organic Solar cell is single organic material or composite of organic materials are placed between two electrodes. One electrode with lower work function worked as Cathode and other one as Anode. To generate exciton in organic layer light should be reached up to organic semiconducting layer, keeping this point in mine one electrode must be transparent in nature.
