Researchers at Nature Energy have achieved a world record of more than 10% efficiency for solar cell material sulphide kesterite (CZTS), as well as a standard-sized kesterite solar cell, according to the University of New South Wales. Led by Dr Xiaojing Hao, the team developed CZTS, replacing costly elements indium and gallium with abundant copper and tin, to create a low cost, non-toxic and flexible thin-film semiconductor material. Dr Hao said she believes it is possible to achieve efficiencies of between 15% and 20%, but said there was much about CZTS that was unknown.
