Conventional crystalline silicon cells could bump up against their theoretical maximum efficiency of 29% as soon as 2020. Sanyo Electric Co. Ltd., for instance, demonstrated ~23% efficiency with a 10cm(2) R&D unit of its heterojunction with intrinsic thin layer (HIT ) cells last year.
It figures that thinner surface contacts, better transparent conductors, and lower defect density can improve performance by several more percentage points, to likely get commercial efficiency up to about as close as practical to the theoretical limit within about ten years.
