引入有机酸可有效去除PbI2·DMSO配合物,加速埋底界面PbI2结晶,这有利于胺盐阳离子插入到PbI2框架中并形成稳定的钙钛矿。经过有机酸处理后,钙钛矿埋底界面处的残余PbI2显著减少,电子传输层与钙钛矿层之间的界面接触得到了改善,非辐射复合降低。 ...
During the delay process, the delay time before annealing the MAI-PbI2-DMSO intermediate phase plays an important role in the nucleation process of perovskite grains inside the intermediate phase. With the extension of the delay time before annealing, the quality of the perovskite film deteriorates...
