Аннотация:Intensive development of solution deposition methods for perovskite solar cells fabrication requires rational optimization of existing methods and search for new effective solvents of different origin involved in key stages of the techniques. We propose a novel approach for rational solvent selection predetermining the character of their interaction with lead halide perovskites in terms of the analysis of donor numbers, dipole moments and Hansen hydrogen bonding parameters. Experimental proofs of the proposed approach provided a cutting-edge categorization of a wide range of possible solvents into four groups: inert, weak, strong, and AX-selective solvents. The resultant approach is a useful tool for perovskite solar cells fabrication.
