Abstract: Alkaline and acidic solutions are used respectively in textures of monocrystalline and multicrystal silicon solar cells due to anisotropic etching of alkaline solutions and isotropic etching of acidic solutions. Two different textures on the surfaces of monocrystalline silicon are fabricated by using two solutions. According to the analysis of the performance of monocrystalline silicon solar cells with different texturing structures, the feasibility of substituting acidic solution instead of alkaline one is discussed.
