Abstract generation in progress

Recently, a research team from the Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences, achieved over 15% photoelectric conversion efficiency with a new type of solar cell material and received certification from an international authoritative organization. The related research results were published in the academic journal “Nature Energy” in the field of international energy and materials. It is understood that the core material of this technology is called Copper Zinc Tin Sulfide Selenide Solar Cell (CZTSSe). Its materials are widely sourced, with abundant main elements in the Earth’s crust, not relying on rare metals, and low material costs; secondly, it is prepared using solution methods, which are cost-effective; as a thin-film solar cell, it uses less material; additionally, this material is safe and environmentally friendly, free of toxic elements, suitable for large-scale applications, and can maintain performance even in complex environments.
