Simulation and optimization of the texture of the front and rear faces of a bifacial silicon solar cell according to the base thickness
Abstract
In this study, we performed a simulation of a bifacial silicon photovoltaic (PV) solar cell using the PC1D numerical software. The dimensions of the texture on the front and rear faces of the solar cell were optimized according to the base thickness. The results clearly demonstrate the impact of the base thickness on the optimal texturing angle of the rear face. Increasing the base thickness leads to a reduction of the optimal texturing angle of the rear face. In addition, texturing of bifacial solar cells improves performance only when the base is thin. In our case, the thickness must be between 100 µm and 130 µm for the texturing of the illuminated surfaces to have a positive impact. An efficiency increase of 8.22% was achieved when the bifacial PV solar cell is textured and illuminated from the rear side.
