Kesterite is one of the most promising light absorber material candidates for potential use in lower-cost thin-film solar cells. Kesterites are comprised of common elements, such as copper, tin ...

Kesterite is a promising addition to the solar tech landscape. It's a combination of copper, zinc, tin, and sulfur, often ...

However, kesterite is still less efficient than CIGS in mass production. The world record for such cells is 12.6%, achieved by Japanese thin-film producer Solar Frontier in 2013.

Scientia Professor Xiaojing Hao and her team from UNSW’s School of Photovoltaic and Renewable Energy Engineering have achieved a best-ever efficiency of 13.2% for high bandgap kesterite solar ...
