Abstract :
In this paper, a device model that describes the current-voltage characteristics of polymer:fullerene bulk heterojunction solar cell has been developed. Two organic PV cells of two different materials are cascaded together to form a tandem organic solar cell. In the design, PPV is implemented as the top cell and P3HT:PCBM blend is used as bottom cell. The simulation has been carried out using Silvaco ATLAS software. The power curve is also derived. Furthermore, the ideal efficiency and the Fill Factor of the tandem cell have been predicted from the curve. The stability of the model is ensured by introducing a thin buffer layer of ZnO coated on top of the solar cell.
