Abstract: Reducing the cost of solar cells and improving the photoelectric conversion efficiency have attracted great attention in recent years. Forming a textured surface using suitable texturing methods was demonstrated as an effective means of increasing the ray trapping efficiency. The effects of different ray trapping structure, as formed on the surface of silicon solar cells to increase the light trapping efficiency, are different on the optical reflectance and absorptance. The aim of this chapter is to study the effects of the novel textured surface formed mechanically on the light trapping efficiency. The base angle size can be controlled mechanically to break through the limitation of crystal structure. In order to calculate the weighted reflectance of different structure, a numerical algorithm was developed in this work. The weighted reflectance was calculated numerically. The light transmission process was tracked. The ray trapping efficiency of novel texture with different parameters was calculated. The weighted reflectance in different conditions was obtained respectively.
