Title:
CRYSTAL GROWTH CONTROL AGENT, METHOD FOR FORMING p-TYPE SEMICONDUCTOR MICROPARTICLES OR p-TYPE SEMICONDUCTOR MICROPARTICLE FILM, COMPOSITION FOR FORMING HOLE TRANSPORT LAYER, AND SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2015/137324
Kind Code:
A1
Abstract:
 According to a first aspect, there are provided: a crystal growth control agent for suppressing any increase in the size of p-type semiconductor crystals, and enabling chemical modification of the surface of p-type semiconductor microparticles; a method in which the crystal growth control agent is used for forming p-type semiconductor microparticles or a p-type semiconductor microparticle film; a composition for forming a hole transport layer of a solar cell; and a solar cell in which the composition for forming a hole transport layer is used. According to a second aspect, there are provided: a composition for forming a hole transport layer that promotes crystallization and refining of a p-type semiconductor, and enables chemical modification of the surface of p-type semiconductor microparticles, even when an organic salt containing an anion other than a thiocyanic acid ion is used (ionic liquid); and a solar cell in which said composition is used. The crystal growth control agent pertaining to the present invention comprises at least one sulfur-containing compound (not including thiocyanates) selected from the group consisting of disulfide compounds and compounds for generating thiolate anions by proton or cation dissociation, and controls the crystal growth of a p-type semiconductor.
