Efficient and stable hybrid perovskite prepared at 60% relative humidity with a hydrophobic additive in anti-solvent
TL;DR: In this paper, a hybrid perovskite (CH3NH3PbI3) in a high relative humidity (RH~60%) ambient condition by using a mixture of ethyl acetate (EA) and 4-Tertbutyl-Pyridine (tBP) as anti-solvent is presented.
Journal ArticleDOI
An efficient solvent additive for the preparation of anion-cation-mixed hybrid and the high performance perovskite solar cells
TL;DR: Steady-state and time-resolved photoluminescence measurements demonstrate fewer defects and less carrier recombination in the perovskite layer with ACN adding, and the simple and green preparation process and the significant improvement of the device performance render this method promising.
