At the European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC 2014), imec and RENA, a leading supplier for wet chemical production tools, presented a novel isopropyl-alcohol (IPA)-free process for the texturing of Cz-Si wafers for high-efficiency silicon solar cell manufacturing at low cost. The process uses monoTEX F, RENA’s next generation texturing additive, instead of the currently used industrial additive IPA. In contrast monoTEX F is a moderating and wetting agent that ...
