COMPOSITE FINE PARTICLES, SOLAR CELL, MEMBER FOR PHOTOELECTRIC CONVERSION ELEMENTS, AND PHOTOELECTRIC CONVERSION ELEMENT

WIPO Patent Application WO/2023/037797

A1

Each of composite fine particles (10) according to the present invention comprises: an inorganic fine particle (1) which has light wavelength conversion ability; a continuous or discontinuous first coating layer (2) which is formed on a part or the entirety of the surface of the inorganic fine particle (1); a second coating layer (3) which is formed on the first coating layer (2); and a third coating layer which is formed on the second coating layer (3). The second coating layer (2) contains a multidentate organic ligand which is an organic compound that has light absorption in a near-infrared or infrared region, while having at least two coordination positions; the first coating layer (1) is an inorganic compound layer or a metal layer, which contains a coordination metal and a transition metal that is the same as or different from the coordination metal; and the third coating layer (3) is an inorganic compound layer or a metal layer, which contains a coordination metal.
