The reporter learned from the Institute of Physics of the Chinese Academy of Sciences that researcher Meng Qingbo's team successfully prepared large-scale copper-zinc-tin/selenium thin-film photovoltaic modules. The photoelectric conversion efficiency of the module reached 13.0%, breaking the world record for the efficiency of such modules, and laying a solid foundation for the industrialization of the next generation of low-cost, environmentally friendly solar cells. The results were recently published in the international academic journal “Nature Materials”.
