Researchers at the University of New South Wales have achieved a world record of between 15% and 20% efficiency for solar cell material sulphide kesterite (CZTS), as well as a standard-sized kesterite solar cell, according to Nature Energy. 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 more than 10%, but said there was much about CZTS that was unknown.
