CIGS solar cell integrated with high mobility microcrystalline Si TFTs on 30X40 cm(2) glass panels for self powered electronics

Abstract

For the first time, we report a novel self-powered TFT panel (30X40cm(2)) by integration of sputtering/non-toxic Se vapor selenization copper-indium-gallium-selenide (CIGS) solar cell (conversion efficiency of 8%) and high electron-mobility (172 cm(2)/V-s) micro-crystalline (mu c)-Si TFTs.
