Surface texturing for suppressing the reflection losses is the first and foremost step in the solar cell fabrication process. Over the years, multi-crystalline silicon (mc-Si) wafer solar cells dominated the PV market due to their cost-effectiveness.
Crystalline silicon wafers serve as fundamental building blocks in the fabrication of solar cells, playing a pivotal role in converting sunlight into electrical energy. To enhance the overall performance and efficiency of solar cells, the surface texturing of crystalline silicon wafers has become a focal point of research and development .
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.
Texturing the surface of crystalline silicon wafers is a very important step in the production of high-efficiency solar cells. Alkaline texturing creates pyramids on the silicon surface, lowering surface reflectivity and improving light trapping in solar cells.
It is obvious that the results obtained after texturing of c-Si wafers by both types of alkali solutions in different conditions are suitable for the mass production of TOPCon solar cells, which is a promising structure of silicon solar cells expected to dominate in solar cell industries in near future.
