Here, we report the bulk growth of layered perovskite MA(2)Pb(SCN)(2)I-2 single crystals by different growth methods in an ambient atmosphere. We also investigate the structural determination and refinements, band gap, and photoluminescence of MA(2)Pb(SCN)(2)I-2 single crystals. More ...
为了最大限度地吸收红外光,需要足够厚度的 Pb-Sn 钙钛矿薄膜,但它引入了结晶不平衡和埋藏界面不良的问题。因此,需要有效的策略来精确控制 Pb-Sn 晶体的垂直生长,并改善埋藏界面以实现高效的电荷传输和提取,以构建高效的 Pb-Sn PSC。 在此,西北工业大学冉晨鑫和黄维院士等人开发了 F-PEA2PbI3SCN 2D 钙钛矿种子层...
perovskite solar modules. As a demonstration, we therefore fabricated such a flexible solar cell of FMC with Pb(SCN)2 on PET substrate at room temperature (Fig. 4c), which exhibits impressive PCEs of 10.55% and 9.48% under reverse and forward scans, respectively, with little hysteresis (...
迄今为止,仅报道了少量层状X位点取代的二维 (2D) RP型钙钛矿。 悉尼大学Anita W. Y. Ho-Baillie和国立台湾大学Chu-Chen Chueh等人报道了第一个无机阳离子类卤化物二维相钙钛矿单晶Cs2Pb(SCN)2Br2。 Cs2Pb(SCN)2Br2是通过反溶剂蒸汽辅助结晶 (AVC) 方法合成的,表现出标准的单层 (n = 1) Ruddlesden-Popper 结...
Perovskite solar cells Additive Visual evidence Molecular interaction Crystallization process Power conversion efficiency 1. Introduction Tremendous interest has been given to the solution-processable organic-inorganic hybrid lead halide perovskite solar cells (PVSCs) [[1], [2], [3], [4], [5]]. Va...
MASCN can not only tune the morphology of the perovskite film but also stabilize the precursor solution via retarding the oxidation of Sn2+ through a strong coordination between SCN? and Sn2+. The Sn/Pb binary inverted PVSCs based on FAPb0.7Sn0.3I3 present a high fill factor of 0.79 and ...
Intriguingly, despite crystallizing in a 2D layered structure, (CH3NH3)2Pb(SCN)2I2 (MAPSI) possesses an ideal band gap of 1.53 eV, close to that of the 3D connected champion hybrid perovskite absorber, CH3NH3PbI3 (MAPI). Here, we identify, using hybrid density functional theory, the ...
