Abstract

In this paper, performance analysis of different structures of organic solar cell is represented. Organic Photovoltaic (OPV) solar cell is recently progressing at a rapid pace due to its low cost, simple manufacturing processing, flexibility and large area devices for future technology. In order to develop efficient and economical photovoltaic cells with good electrical and optical properties, more attention is given to development of better materials and novel structures. Therefore, in this paper different structures of organic solar cell by using different organic materials have been simulated and studied in order to find the best material for the device. The performance of OPVs is discussed on the basis of its basic performance parameters, i.e., short circuit current density, open circuit voltage, fill factor, and power conversion efficiency. The simulation of OPVs is performed in Silvaco ATLAS TCAD tool. Basic equations used by the software is also covered in this paper. This paper shows that bulk heterojunction has good performance.
