Solar Frontier K.K. has set a new world record for thin-film solar cell efficiency. In joint research with the National Research and Development Agency's New Energy and Industrial Technology Development Organization (NEDO) of Japan, Solar Frontier achieved 22.9% conversion efficiency on a 1cm2 cell using its CIS technology. Independently verified by the National Institute of Advanced Industrial Science and Technology (AIST) in November, this record achieved 0.3 percentage points over the current world record of 22.6% that was set by the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) in February 2016.
 
This achievement was made through such technologies as CIS absorber engineering and enhanced surface treatment of the absorber layer, which demonstrate the steady progression of Solar Frontier's thin-film technology. Solar Frontier expresses its gratitude to everyone for their cooperation in achieving this record, namely NEDO and AIST.
