Oxidized disulfide oil (ODSO) solvent compositions are derived from by-product disulfide oil (DSO) compounds produced as by-products from the generalized mercaptan oxidation (MEROX) processing of a refinery feedstock. The oxidized disulfide oil (ODSO) solvent compositions comprise at least a primary oxidized disulfide oil (ODSO) compound selected from either water soluble or water insoluble oxidized disulfide oil (ODSO) compounds and in some embodiments at least 0.1 ppmw of a secondary oxidized disulfide oil (ODSO) compound that is a water soluble oxidized disulfide oil (ODSO) compound.

A method for preparing photoactive perovskite materials. The method comprises the steps of: introducing a lead halide and a first solvent to a first vessel and contacting the lead halide with the first solvent to dissolve the lead halide to form a lead halide solution, introducing a Group 1 metal halide a second solvent into a second vessel and contacting the Group 1 metal halide with the second solvent to dissolve the Group 1 metal halide to form a Group 1 metal halide solution, and contacting the lead halide solution with the Group 1 metal halide solution to form a thin-film precursor ink. The method further comprises depositing the thin-film precursor ink onto a substrate, drying the thin-film precursor ink to form a thin film, annealing the thin film; and rinsing the thin film with a salt solution.
