厦门大学谭元植课题组与南方科技大学夏海平和何凤---纳米石墨烯-碳龙配合物作为阴极界面层有效提高有机太阳能电池效率提超过18%

界面工程是有效提高非富勒烯太阳能电池(NFSC)光伏性能的关键方法。本文报道了一系列包含金属-纳米石墨烯的大过渡金属，涉及-dp-pp-共轭体系，通过 碳龙和对二乙炔基六苯并晕酮的加成反应。共轭延伸设计用于优化这些金属-纳米石墨烯分子的p共轭，这些分子用作醇溶性阴极界面层(CIL)材料。随着p共轭的扩展，基于PM6:BTP-eC9 的NFSC的功率转换效率(PCE)从16%增加到超过 18%，提供了最高记录的PCE。通过X射线晶体学分析、界面接触法、形貌表征和载流子动力学推断，六苯并晕苯-苯乙烯基改性可以有效提高有机太阳能电池（OSCs）的短路电流密度（Jsc）和填充因子，主要是由于强且有序的电荷转移、更匹配的能级排列、活性层和电极之间更好的界面接触以及受调节的形态。因此，极大地促进了载流子传输，同时阻碍了载流子复合。这些新的CIL材料广泛地能够增强其他系统中OSC的光伏特性，这为作为更高质量OSC的CIL提供了有希望的潜力。
