Simulation of Organic Solar Cells by AMPS-1D Program

Abstract

The program AMPS-1D has been successfully used to study inorganic solar cells. In this work the program has been used to optimize the performance of the organic solar cells. The cells considered consist of [MDMO-PPV] and [P3HT] as electron donors, and [PCBM] as electron acceptor.

The results are found to be in a good agreement with the experimental results, obtained from the literature.

The results have shown that the optimum thickness of the solar cell is about 120 nm. The optimum energy difference between the lowest unoccupied molecular orbital of the electron donor and the electron acceptor has been about 0.5 eV. The results have also shown that the open circuit voltage decreases with temperature at a rate of about 0.55 mV/0K.
