To prepare the high-thickness and Br-doping CH3NH3PbI3 − xBrx thin film, the high concentration (1.7 M) PbI2·DMSO complex precursor solution in DMF was successfully prepared by repeating the cycle of PbI2-dissovling and DMSO-adding. The influence of PbI2·DMSO complex precursor ...
Planar perovskite solar cells (PSCs) fabricated by intramolecular exchange with PbI2(DMSO) and PbI2(NMP) complexes and the high performance of these cells ... Y Jo,KS Oh,M Kim,... - 《Advanced Materials Interfaces》 被引量: 13发表: 2016年 PbI2–HMPA Complex Pretreatment for Highly Reproduc...
However, how the lead halide complex affects the crystallization kinetics and thus the film quality of perovskite has not been systematically studied. Herein, two PbI2(X) complexes with different coordination strength of ligand X in complexation with PbI2 (PbI2(DMF) and PbI2(DMSO)) are synthesized...
