Application of the SILVACO/ATLAS software package in modeling and optimization of state-of-the-art photovoltaic devices

In this paper a new method for developing a realistic model of any type of solar cell is presented. Taking into account the high cost of research and experimentation involved with the development of advanced cells, we present here this novel methodology. In our opinion, the introduction of this modeling technique to the photovoltaic community will prove to be of great importance in aiding the design and developing of advanced solar cells. A model of an InGaP/GaAs multi-junction solar cell is prepared and is fully simulated. The major stages of the process are explained and the simulation results are compared to published experimental data. The flexibility of the proposed methodology is demonstrated and example results are shown throughout the whole process.
