Abstract: A coating liquid includes aluminum phosphate, a nonionic surfactant, and water and/or water-soluble solvent that dissolves or disperses the aluminum phosphate and the nonionic surfactant. An amount of the nonionic surfactant is preferably 1 vol % or more and 10 vol % or less. The nonionic surfactant is preferably at least one selected from the group consisting of ester, ether, alkylglycoside, octylphenol ethoxylate, pyrrolidone, and polyhydric alcohol. Applying such a coating liquid to a surface of a thermoelectric member, and drying and firing the coating liquid enables formation of a dense antioxidant film containing aluminum phosphate on the surface of the thermoelectric member.

Abstract: A thermoelectric element includes a thermoelectric member made of thermoelectric materials and having a through hole, a pipe inserted into the through hole for making fluid flow, and a soaking member provided to the side of the thermoelectric element. The pipe and the soaking member respectively also function as an electrode of the thermoelectric member. A surface of the soaking member includes a blackened surface and a mirror surface. A thermoelectric generation system includes a container having a lighting window, the thermoelectric element housed in the container, a fluid feeder for feeding fluid into the pipe, and a power consumption source that consumes electric power generated by the thermoelectric element. The thermoelectric element is housed in the container so that the blackened surface is located under the lighting window.

Abstract: A composite thermoelectric material includes: a thermoelectric material of an intermetallic compound series; and a film that is coated over the whole or a part of the surface of the thermoelectric material and contains aluminum phosphate (AlPO4) as a main component. Such a composite thermoelectric material is obtained by: applying a coating liquid obtained by dispersing or dissolving aluminum phosphate (AlPO4) into a solvent over the surface of a thermoelectric material; drying the coating liquid and obtaining a precursor film; and firing the thermoelectric material over which the precursor film is formed.

Abstract: The present invention is to provide a pigment dispersion liquid which has excellent pigment dispersion stability and high productivity even in the case of using a fine pigment and having high pigment concentration; a method for producing the pigment dispersion liquid; a color resin composition which has excellent pigment dispersion stability, causes no clogging problem, has excellent adhesion, and is able to form color layers with high pigment concentration, with accuracy; and a color filter comprising the resin composition. Disclosed is a method for producing a pigment dispersion liquid, comprising the step of dispersing a pigment by mixing at least a pigment (A), a polymer (B) having tertiary or lower amines, an amine-reactive low molecular compound (C), and a dispersion medium (D), and dispersing the pigment (A) while reacting the polymer (B) with the low molecular compound (C), and a pigment dispersion liquid produced by the production method.

Abstract: An electrode for a photovoltaic device includes a Mo layer and a sulfurization-resistant layer formed on the Mo layer. The sulfurization-resistant layer contains at least one element X selected from a group consisting of Nb, Ti, Ta, Au, V, Mn, and W.
