December 20 (Renewables Now) - Solar Frontier KK has achieved a 22.9% conversion efficiency on a 1 sq cm (0.155 sq inch) solar cell using its copper indium diselenide (CIS) technology.

The accomplishment marks a new world record for thin-film solar cell efficiency, the Japanese CIS solar panel manufacturer said on Wednesday. It is a result of joint research with the National Research and Development Agency's New Energy and Industrial Technology Development Organization (NEDO) of Japan and has been verified by the National Institute of Advanced Industrial Science and Technology (AIST) in November.

The 22.9% efficiency beats the current record of 22.6% that was established by the Center for Solar Energy and Hydrogen Research Baden-Wuerttemberg (ZSW) in February 2016, Solar Frontier said. The company, a subsidiary of Showa Shell Sekiyu KK (TYO:5002), achieved the increased efficiency via CIS absorber engineering and enhanced surface treatment of the absorber layer.

Solar Frontier previously reported 22.3% conversion efficiency at the end of 2015.
