CIGS record broken
Stuttgart solar researchers bring a world record to Germany with a 20.1 percent efficient thin-film solar cell. (...) The record-breaking solar cell, made of copper, indium, gallium and selenium - or CIGS for short - was produced in the ZSW research laboratory. (...) The US research institute NREL has held this record for 16 years. (...)
The area of the world record cell is 0.5 square centimetres. The solar cell was produced in a CIGS laboratory coating plant using a modified co-evaporation process, which in principle can be scaled up to a commercial production process.
