25.2%！钙钛矿光伏电池效率已达理论最高效率八成
钙钛矿 光伏电池效率 最高效率
2021/3/17
麻省理工学院（MIT）的一组研究人员利用新方法将钙钛矿的效率提高到了25.2%，超过了当今典型硅电池的效率（通常在20%到22%之间），为进一步的改进奠定了基础。众所周知，钙钛矿是最终取代硅作为太阳能电池板的首选材料。它们提供了在低成本、低温环境下制造超薄轻质柔性电池的潜力，但由于它们将阳光转化为电能的效率落后于硅和其他一些替代品，其前景一直受限。
近日，教育部办公厅印发《关于公布2020年度国家级和省级一流本科专业建设点名单的通知》（教高厅函〔2021〕7号），暨南大学经济统计学等13个专业入选国家级一流本科专业建设点，知识产权等12个专业入选省级一流本科专业建设点。
2020年6月30日，Wiley旗下高水平期刊Advanced Energy Materials（IF=25）在线发表了题为“Achieving 17.4% Efficiency of Ternary Organic Photovoltaics with Two Well-Compatible Nonfullerene Acceptors for Minimizing Energy Loss”的最...
