澳大利亚新南威尔士大学研究团队在太阳能技术领域取得重要突破：他们找到一种稳定的有机材料，可 在硅太阳能电池中实现"单线态裂分"效应。这项可将阳光"一分为二"的新技术，有望显著提升光电转换 效率。相关成果发表于新一期《ACS能源快报》。 "单线态裂分"是一种独特的物理过程，能让一个光子分裂成两个能量包，相当于把阳光的能量"分拆使 用"，从而把原本以热形式浪费的光能转化为额外电力。研究团队表示，通过在硅电池表面叠加一层超 薄有机分子层，入射的高能光子可在该层内发生裂分，生成两个低能激发态，并向下方的硅层注入更多 电荷，显著提高电流输出。 目前，大多数商业化硅太阳能电池的最高转换效率约为27%，理论上限为29.4%。高能光子（如蓝光） 的能量常被浪费为热。引入"单线态裂分"机制后，这部分损耗的能量可被重新利用，理论效率有望提升 至45%。 此前国际研究团队曾用四苯等分子实现裂分，但材料稳定性不足。此次团队采用了双吡咯并萘啶酮 （DPND），这种工业颜料类有机材料具备优异耐久性，能在空气和潮湿环境下长期稳定工作。研究已 证明，DPND可与硅电池兼容，实现能量倍增。 团队表示，这是首次在硅材料上用基于工业颜料的稳定有机 ...
