不同表面织构对单晶硅太阳电池性能的影响

Effects of different texture on performance of monocrystalline silicon solar cells

摘要: 由于碱溶液具有各向异性腐蚀和酸溶液具有各向同性腐蚀的特性，它们被分别用于单晶硅和多晶硅太阳能电池表面织构的制备。使用这2种溶液在单晶硅表面形成2种不同的绒面结构。通过对具有不同绒面结构电池的性能进行分析，讨论了在单晶硅太阳电池的工业化生产中用酸溶液代替碱溶液进行织构制备的可行性。

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.
