Solar Frontier K.K. of Tokyo, Japan, a provider of copper indium selenide (CIS) solar energy solutions, reported that the company set a new world record for thin-film solar cell efficiency. The firm collaborated with the National Research and Development Agency’s New Energy and Industrial Technology Development Organization (NEDO) of Japan on joint research to achieve 22.9% conversion efficiency on a 1cm2 CIS solar cell. Solar Frontier notes that the National Institute of Advanced Industrial Science and Technology (AIST) independently verified the record in November.
Solar Frontier Record 0.3 Percentage Points Over the Previous Record
Furthermore, the company says that this record increases the previous record by 0.3 percentage points over the current world record of 22.6% that the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) set in February 2016. Improvements in surface treatment of the absorber layer and absorber engineering made the record possible according to the company.
Solar Frontier indicated that it will make use of its research and development efforts in the company production of actual output volume. Also, the company says it intends to build on the research results in pursuit of the CIS thin-film solar technology potential.
