Texturing process of c-Si wafers

Abstract

This chapter focuses on process technology for making texture surface in c-Si solar cells. Starting with c-Si crystal structure and role of crystal planes, wafer type and orientation in deciding the chemical process chemistry for texturing has been covered. Also, chemical processes used for achieving different shape of textures on surface in mono- as well as multi c-Si wafers has been discussed along with the principle behind the process, which makes texturization possible. At the end, practical implications involved in chemical texturing based technology has been discussed in context of manufacturing of the c-Si solar cells.
