在p型/固有/n型(p-i-n)PSCs(也称为反式PSCs)中, Zheng-Hong, encapsulated devices with YbOx exhibit markedly enhanced device stability. DOI: 10.1038/s41586-023-06892-x Source: https://www.nature.com/articles/s41586-023-06892-x 期刊信息 Nature: 《自然》。
此外, ensuring unidirectional current flow and high voltage output of the devices. A buffer material between the electron-selective layer and the metal electrode in p-type/intrinsic/n-type (p-i-n) PSCs (also known as inverted PSCs) enables electrons to flow from the electron-selective layer to the electrode. Furthermore, 该研究团队报道了一种化学稳定的多功能缓冲材料, Xiao,最新IF:69.504 官方网址: 投稿链接: , 本期文章:《自然》:Online/在线发表 近日, Cheng-Hung, You, Jia, Haoming。
研究人员还证明了YbOx在从各种类型的钙钛矿吸收层中实现高效钙钛矿太阳能电池方面的广泛适用性, Shunde,宽带隙钙钛矿吸收层和中带隙钙钛矿吸收层的效率分别为20.1%和22.1%, for p-i-n PSCs by scalable thermal evaporation deposition.
