PURPOSE: A manufacturing method of a photoactive layer is comprises to be able to manufacture multi-source chalcogen compound (a photoactive layer) with high quality through simple, safe and convenient processes, or to be able to manufacture a photoactive layer made of coarse grains, having an excellent compositional stability and uniformity, and an elaborate fine structure. CONSTITUTION: Ink includes composite particles in which a first chalcogen compound of a metal of group 11, and a second chalcogen compound of a metal of group 11, which has a lower melting point than the first chalcogen compound, are mixed in a single particle; and a third chalcogen compound of one or more than two selected from group 12-14. A manufacturing method of a photoactive layer for a solar cell comprises (i) a step of forming a coated film by coating the ink on a substrate; and (ii) a step of manufacturing a multi-source chalcogen compound film of a metal of group 11, and one or more than two elements selected from group 12-14, by heat-treating the coated film. |
