Because of its symmetrical a-Si/c-Si/a-Si structure, silicon heterojunction (SHJ) cell technology offers the possibility to use much thinner wafers, and thus to reduce material and production cost. In order to evaluate the industrial feasibility of these thinner heterojunction cells, wafers from the standard thickness of 160μm down to 40μm were processed on the heterojunction pilot line at CEA-INES.
