Herein, an ultrafast random-pyramid texturing process is proposed for monocrystalline silicon (mono-Si) solar cells by combining metal-catalyzed chemical etching (MCCE) and the standard alkaline texturing process.
Surface texturing of silicon wafers for solar cells is considered one of the important processes to improve the performance of solar cells. This process ultimately contributes to improving the overall efficiency of the cell by optimizing light absorption, charge separation, and charge transfer.
Up to now, monocrystalline silicon solar cells occupy the main position in the photovoltaic market. As a semiconductor device based on photovoltaic effect, improving the conversion efficiency of solar cells have always been the development direction [1, 2].
To improve the photoelectric conversion efficiency of monocrystalline silicon solar cells, the influence of the pyramidal texture uniformity on the defects in the monocrystalline silicon cells was analyzed by simulation, and the uniformity of the pyramidal texture was quantitatively characterized with the uniformity coefficient.
Silicon surface texturing is an effective way of light trapping for solar cells application [9, 12]. Light trapping is typically achieved by altering the way the light travels by making it incident on an angled surface in the solar cell.
The experimental results show that the optimized monocrystalline silicon cell achieved a pyramidal texture with a maximum uniformity coefficient. In addition, the reflectivity of the monocrystalline silicon cell reached a minimum value, and the photoelectric conversion efficiency reached a maximum value.
