IEDM 2011: Solar cell records for CIGS, c-Si


IEDM isn’t just about semiconductors anymore — it’s branched out into related technologies, even solar cell structures. Taiwan’s National Nano Device Laboratories will show off a two-sided solar cell integrated with thin-film transistors built with sodium-free and Cd-free (n-type ZnS buffer layer) green technologies, resulting in 6" CIGS (CuInGaSe2) cells that topped out at 11% conversion efficiency at 500
