ceramic substrate for thin-film crystalline silicon solar cells

摘要

In a process for producing a solar cell support wafer, consisting of a reaction bonded silicon carbide-based ceramic substrate layer, a crystalline silicon top layer and optionally an intermediate barrier layer, reaction bonding of the substrate layer and formation of the silicon top layer are carried out in a single heat treatment operation. Also claimed is a solar cell support wafer consisting of a reaction bonded silicon carbide-based ceramic substrate layer, a crystalline silicon top layer and optionally an intermediate barrier layer.
