Solar Frontier hits new thin film cell efficiency record


Solar Frontier has set a new efficiency record for its Copper/Indium/Selenium (CIS) based cell technology. The company worked with the Japanese Government’s Energy and Industrial Technology Development Organization (NEDO) to achieve a conversion efficiency of 22.9% on a 1cm² cell.

This record has been confirmed by the National Institute of Advanced Industrial Science and Technology in Japan, and adds 0.3% to the previous record, set by the Center for Solar Energy and Hydrogen Research, Baden Württemberg (ZSE) in February 2016, and 0.6% to Solar Frontier’s previous record of 22.3%, achieved in December 2015.

The record is in line with Solar Frontier’s reported plan to focus on R&D and products for the Japanese residential market, where limited space make efficiency a key consideration. The development was made possible, says Solar Frontier, thanks to CIS absorber engineering, and enhanced surface treatments of the absorber layer.

Solar Frontier previously reported stable demand for its products in 2017, but has struggled with falling module prices. It is currently undergoing a process of consolidation to bring all production to its flagship 900 MW facility, and focusing on selling its products in Japan, where it can achieve greater profits.
