据科技日报,新型薄膜光伏技术研发取得重要进展。据中国科学院物理研究所消息,该所孟庆波研究员团队成功制备出大面积铜锌锡硫硒薄膜光伏组件,组件光电转换效率达到13.0%,刷新了该类组件效率的世界纪录,为下一代低成本、环境友好型太阳能电池产业化奠定坚实基础。相关研究成果在线发表于国际学术期刊《自然·材料》杂志。铜锌锡硫硒是一种新型薄膜光伏材料,由铜、锌、锡等地球储量丰富、价格低廉且环境友好的元素组成,被认为是下一代可持续太阳能电池的重要方向。近年来,孟庆波团队已先后10次刷新该类电池效率的世界纪录。然而,要将这种“实验室明星”推向实际应用,一个关键难题摆在面前:器件尺寸一旦放大,薄膜均匀性就急剧下降,效率也随之“缩水”。
