Researchers at the University of New ##tech Wales 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 Nature Energy . Led by Dr Xiaojing Hao , the team developed CZTS , replacing costly elements indium and gallium with abundant copper and zinc , to produce a low cost , non - toxic and flexible thin - film composite material . Dr Hao said she believed it is possible to achieve efficiencies of between 10 % and 20 % , but said there was much about CZTS that was unknown .
Researchers at the University of New South Wales 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 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 between 15% and 20%, but said there was much about CZTS that was unknown.
