September 27th, 2014 by James Ayre A new CIGS thin-film solar cell conversion efficiency record was recently achieved by researchers at the Center for Solar Energy and Hydrogen Research (ZSW) in Stuttgart. The new conversion efficiency record of 21.7% beats the previous record of 21% — that was set earlier this year by the Fraunhofer Institute for Solar Energy Systems — pretty substantially, and represents a notable improvement in the technology. As noted by the head of ZSW’s PV division, Michael Powalla, the new record means that the efficiency lead of CIGS over multicystalline PV cells has been expanded to 1.3% — a pretty substantial lead. One that Powalla thinks improves the likelihood of CIGS technology growing to be a bigger piece of the total solar market. Powalla states: “Our advances once again confirm the tremendous technological potential of CIGS thin-film photov...
