摘要
A new texturization process based on a uniform, isotropic and slow removal of silicon using a composition of sodium hydroxide (NaOH) and sodium hypochlorite (NaOCl) solution at an elevated temperature is developed recently for multicrystalline silicon solar cells. This process is applied in our regular production line and it immediately replaces the old popular industrial process of texturization using NaOH solution, alcoholic NaOH solution anti hydrochloric acid solution in different steps at a higher temperature. Also the gain in module wattage efficiency at global AM1.5 1 SUN condition is nearly 10% in final value. In addition it has become finally an energy efficient and environment friendly texturization process for multicrystalline silicon wafers for commercial use. In this paper we are going to describe the cost effectiveness and environment friendly aspects in details.
