The sawed silicon wafers will be cleaned and afterwards the alkaline texturing process takes place. The texturing process will etch surface of silicon, that we obtain a surface with pyramids. This will reduce the reflection of the light to maximize the light absorption into the silicon material, leading to a higher efficiency of the solar cells.
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.
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 .
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.
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.
Without any additive the surface of the silicon wafer will be etched in the alkaline process only planar, while additives influence the etching direction. With texturing additives like monoTEX ® the anisotropic etching is preferred and we obtain a etched surface with homogenously distributed pyramids and a low reflection.
