A research group led by Prof. Meng Qingbo from the Institute of Physics (IOP) of the Chinese Academy of Science (CAS) and Prof. Xin Hao from Nanjing University of Posts and Telecommunications has reported 13.8% certified efficiency of emerging kesterite solar cells. The study was published in Nature Energy on April 13.
Kesterite Cu2ZnSn(S, Se)4 (CZTSSe), as one of the most competitive thin-film photovoltaic materials, exhibits attractive advantages such as earth-abundant elemental reserves, optimal bandgaps for photovoltaic (PV) technology, and high stability.
