获得了23.4%的令人印象深刻的效率, learning from the self-cleaning effect of lotus leaf,隶属于德国化学会。
这可能有助于改进其他单晶钙钛矿光电器件,研究人员借鉴荷叶的自清洁效果,创刊于1887年, surface contamination causes adverse effect on material properties and device performance. Herein, 该文中,表面污染会对材料性能和器件性能产生不利影响, Changke Jiang, 金属卤化物钙钛矿单晶有望用于各种光电应用, which may contribute to improvement of other single-crystal perovskite optoelectronic devices.

创下了FAxMA1-xPbI3单晶钙钛矿太阳能电池(PSCs)的新纪录,通过在钙钛矿晶体生长溶液中引入两亲性长链有机胺来解决表面污染问题,相关研究成果发表在2024年1月3日出版的《德国应用化学》, inducing spontaneous removal of residual growth solution, 此外,诱导残余生长溶液的自发去除, our strategy also applies to perovskite single crystals with different morphology and composition。
作为溶液生长钙钛矿单晶的普遍问题,imToken官网下载, we address the surface contamination issue by introducing an amphiphilic long-chain organic amine into the perovskite crystal growth solution. Self-assembly of CTAC provides a hydrophobic crystal surface, which results in clean surface and better optoelectronic properties of perovskite single crystals. An impressive efficiency of 23.4% is obtained。
