A new world record for thin-film solar cell efficiency was achieved by Solar Frontier in joint research with the The 1 sq cm cell beat the previous conversion efficiency record by 0.3 percent. Source: Solar FrontierNational Research and Development Agency's New Energy and Industrial Technology Development Organization (NEDO) of Japan. A conversion efficiency of 22.9 percent was documented on a 1 cm² cell based on the company’s copper-indium-selenium (CIS) photovoltaic technology.

This efficiency level surpasses the previous record of 22.6 percent, established by the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) in February 2016, by 0.3 percentage points. The energy conversion gain is attributed to improvements to the CIS absorber layer and junction formation process, bringing the company closer to its goal of exceeding 30 percent efficiency.

Solar Frontier’s CIS modules generate more energy (kilowatt-hours per kilowatt-peak) compared to crystalline silicon in real-world conditions.
