Researchers at the University of New South Wales (UNSW) have shattered the world record for the efficiency of kesterite solar cells, which is considered a promising alternative to traditional ...

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.

A group of researchers led by the Chinese Academy of Sciences (CAS) has fabricated a kesterite (CZTSSe) solar cell that achieved a maximum power conversion efficiency of 14.6% and a certified ...
