COMPOUND SEMICONDUCTOR PARTICLE COMPOSITION, COMPOUND SEMICONDUCTOR FILM AND METHOD FOR SAME, PHOTOELECTRIC CONVERSION ELEMENT, AND SOLAR CELL

摘要

Disclosed is a chalcopyrite compound semiconductor particle composition which can increase the photoelectric conversion efficiency of a compound semiconductor film. The disclosed compound semiconductor particle composition comprises: particles (A) which are formed from a plurality of at least one kind of semiconductor particles, and which have a number average particle diameter of 100nm or more, as calculated with a transmission electron microscope; and filling (B), which is formed from a plurality of at least one kind of semiconductor particles, is formed from particles (BX) which have a smaller number average particle diameter than particles (A) as calculated with a transmission electron microscope, and/or a non-solid semiconductor precursor composition (BY) which forms a solid semiconductor on heating. Both (A) and (B) are formed from chalcopyrite compound semiconductors each represented by the general formula below, and filling (B) fills in the gaps between particles (A). (i) LMX2 (therein, L represents at least one kind of group IB element, M represents at least one kind of IIIB group, and X represents at least one kind of VIB group).
