Abstract

Perovskite Solar Cells

A comparative study of cis- and trans-hydroxylated cyclohexylammonium ligands in perovskite solar cells reveals distinct interfacial interactions with [PbI₆]⁴⁻ octahedra. The cis isomer preferentially anchors onto the 3D perovskite surface, forming a 2D/3D heterojunction that enables effective defect passivation and promotes efficient hole extraction across the perovskite–HTL interface, thereby enhancing charge transport and device performance. More in article number 2501564, Yun Seog Lee and co-workers.

基于环己基配体的二维/三维钙钛矿太阳能电池界面钝化增强的空间原子排列（Small 30/2025）

钙钛矿太阳能电池钙钛矿太阳能电池中顺式和反式羟基化环己基铵配体的比较研究揭示了与[PbI6]4−八面体的不同界面相互作用。顺式异构体优先锚定在3D钙钛矿表面，形成2D/3D异质结，实现有效的缺陷钝化，并促进钙钛矿- html界面上有效的空穴提取，从而增强电荷传输和器件性能。详见文章编号2501564，Yun Seog Lee及其同事。
