Solar Frontier announced thin-film solar cells efficiency by 22.9 percent

Solar Frontier Kabushiki Kaisha announced it has upgraded the conversion efficiency of CIS-based thin film solar cells by up to 22.9%. The developer and manufacturer of thin film solar cells headquartered in Minato in collaboration with New Energy and the Industrial Technology Development Organization (NEDO) in research to open up future production opportunities.

Showa Shell Sekiyu's Solar Frontier KK says solar cells as wide as about 1cm have a 22.9% efficiency as the world's highest convertible thin-film solar cell. The efficiency has been tested by the National Institute of Advanced Industrial Science and Technology (AIST) in November 2017.

Efficiency is 0.3 points higher than the previous world record conducted by the German Center for Solar Energy and Hydrogen Research Baden-Wurttemberg (ZSW) which set a 0.5cm cell that had a 22.6% conversion in February 2016.

Solar Frontier achieved efficiency records through technologies such as CIS absorbent techniques and improved surface treatment. The company announced in February 2017 that it has achieved 19.2% conversion efficiency in 30x30cm CIS-based solar cell sub-module and 19.8% efficiency in 7x5cm mini module.

The conversion efficiency of 19.2% is equivalent to 210-220W per panel. The company said the commercialization of the product in high efficiency at 200W per panel will enter production at Kunitomi Factory in Miyazaki Prefecture. The 22.9% conversion efficiency allows output of over 260W or equivalent crystalline silicon solar panels.
