چکیده

The purpose of this study is to determine the optimum location for intermediate band in the middle of band gap of an ideal solar cell for maximum performance. By changing the location of the intermediate band, output current and therefore performance can be changed. Choosing the best location in terms of solar cell energy gap and how to change the performance by means of the location of intermediate band has the important role in the energy band gap engineering. This matter in the known methods of the intermediate bands realization such as quantum well and quantum dots can be used for selecting the type of semiconductor in quantum well or quantum dot and also for selecting dimension of quantum dot or quantum well. Conclusion of this paper is by increasing energy gap, the optimal location of intermediate band for cells with one intermediate band, will be closer to the middle of the energy gap.
