Japan-based Solar Frontier has achieved a solar cell efficiency of 22.3% with its copper indium selenium (CIS) thin-film technology.
Through joint research with the New Energy and Industrial Technology Development Organization of Japan, Solar Frontier achieved the results on a 0.5cm² cell. The Fraunhofer Institute has independently verified the test.
‘This is a proud achievement for Solar Frontier and a significant advancement for our CIS technology,’ says Satoru Kuriyagawa, chief technology officer of Solar Frontier. ‘We achieved our latest record through improvements to the CIS absorber layer and junction formation process. This latest advancement brings us a step closer toward realizing Solar Frontier's long-term goal of exceeding 30% efficiency using CIS.’
