Solar Frontier Achieves Record CIS Efficiency
CIS solar energy provider Solar Frontier has set a new record for thin-film solar cell efficiency. In joint research with the New Energy and Industrial Technology Development Organization (NEDO) of Japan, Solar Frontier achieved 22.3 percent conversion efficiency on a 0.5cm2 cell using its CIS technology.
This is an increase of 0.6 percentage points over the industry's previous thin-film record of 21.7 percent. The Fraunhofer Institute, Europe's largest organisation for applied research, has independently verified this result.
"This is the first time that CIS has crossed the 22 percent efficiency boundary - a level not yet surpassed by any other thin-film or multi-crystalline silicon technology," said Satoru Kuriyagawa, CTO 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 realising Solar Frontier's long-term goal of exceeding 30 percent efficiency using CIS."
