摘要
光伏器件中光生电荷转移是界面电荷分离、复合、载流子输运等多个动力学过程的相互耦合,以染料敏化和钙钛矿太阳能电池(分别简称DSCs和PSCs)为代表的新型有机-无机复合太阳能电池电荷转移动力学过程跨越了多个时间和空间尺度。近些年来,我们围绕DSCs和PSCs中的固-液界面及固-固界面电荷交换、电子/离子输运及界面耦合开展了系统研究,内容包括:(1)为了进一步提高DSCs对电极电催化活性和贵金属原子利用率,开展了单原子电催化研究并探索合成了多种高效非Pt对电极材料,实现了原子/分子尺度催化位点的精准构筑并发展了过渡金属化合物对电极材料多尺度构筑和性能调控方法;(2)为了实现PSCs的低温制备,构筑了无机非晶半导体材料电子转移层并发展了其性能调控方法;(3)为了加快DSCs多孔光阳极中载流子的输运并增强固-液界面耦合作用,通过温和可控的方法构筑出了高度双连续孔结构和电子快速输运通道,离子/电子扩散系数以及器件光电性能因此获得大幅提升。
The fundamental research of our group has been performed on organic-inorganic photovoltaics, especially on the regulation of charge transfer dynamics. To facilitate the solid-liquid interface charge transfer between counter electrode and electrolyte in dye-sensitized solar cells(DSCs), we carried out research on single-atom electrocatalysis, multiscale construction and property regulation of non-Pt counter materials. To facilitate the interface charge separation and transport in perovskite solar cells(PSCs), low-temperature fabrication of charge transfer layers based on amorphous semiconductor or carbon material were realized, and strategies on property regulation were put forward as well. For the photoanode in DSCs, highly bi-continuous pore-structures and pathway were constructed for fast carrier transport and strengthened interface coupling.
