效率突破15% 我国新一代太阳能电池研究取得新进展

Core Viewpoint - A research team from the Qingdao Institute of Bioenergy and Process Research, Chinese Academy of Sciences, has achieved over 15% photovoltaic conversion efficiency with a new type of solar cell material, receiving international certification [1] Group 1: Technology and Material - The core material used in this technology is Copper Zinc Tin Sulfide Selenium solar cells (CZTSSe) [1] - The primary elements of CZTSSe are abundant in the Earth's crust, making it a low-cost material that does not rely on rare metals [1] - The production method is based on a solution process, which further reduces manufacturing costs [1] Group 2: Environmental and Performance Aspects - The thin-film solar cells require less material, contributing to lower overall costs [1] - The material is safe and environmentally friendly, containing no toxic elements, making it suitable for large-scale applications [1] - The performance of the solar cells remains stable even in complex environmental conditions [1]
