Abstract

The optimization of a mono-crystalline silicon solar cell is complicated due to various competing physical mechanisms that determine its performance. In this paper a three-dimensional (3D) electrical simulation template for mono-crystalline silicon solar cell optimization is developed using Synopsys Sentaurus tool suite, and is used to demonstrate an optimization space of over 1 percent in terms of cell power conversion efficiency. The key design parameters include rear point contact area coverage, substrate doping concentration, cell thickness, and the junction. Comparison between three-dimensional analysis and the simplified two-dimensional and one-dimensional cases is also provided.
