Solar Frontier K.K., a leading provider of CIS solar energy solutions, 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 23.35% conversion efficiency on a 1cm² cell using cadmium (Cd)-free CIS technology. The result was independently verified by the National Institute of Advanced Industrial Science and Technology (AIST) in November 2018.
 


 
This achievement was made through the research and development of such technologies as CIS absorber engineering and enhanced surface treatment of the absorber – used together with Solar Frontier’s proprietary Cd-free CIS thin-film technology.
 
The conversion efficiency achieved here represents a 0.4 percentage point increase over the previous world record of 22.9% that Solar Frontier set for Cd-containing CIS thin-film solar cells in November 2017.
 
Solar Frontier’s thin-film solar cells stand out among other solar cell technologies for the environmental characteristics that they offer, achieving high conversion efficiency while saving resources by foregoing the use of Cd, lead and other such chemical elements.
