Abstract
Official abstract text for this publication.
A method of producing a metal chalcogenide dispersion usable in forming a light absorbing layer of a solar cell, the method including: a metal chalcogenide nano particle formation step in which at least one metal or metal compound selected from the group consisting of a group 11, 12, 13, 14 or 15 metal or metal compound, a water-containing solvent and a group 16 element-containing compound are mixed together to obtain metal chalcogenide nano particles; and an addition step in which a compound (1) represented by general formula (1) is added to the metal chalcogenide nano particles, thereby obtaining a metal chalcogenide dispersion (wherein R 1 to R 4 each independently represents an alkyl group, an aryl group or a hydrogen atom; provided that at least one of R 1 to R 4 represents a hydrocarbon group).
