The wet chemical treatment of monocrystalline silicon wafers, said method comprising texturing, represents one of the fundamental steps of manufacturing techniques of high-efficiency solar cells. As part of this work, methods for texturing single-crystal silicon wafers for solar cells were studied.As a result of studies, the optimal parameters of texturing technology for the studied samples were determined. The main type of etchant for texturing processes, which is a solution of KOH with isopropanol, is also determined.
