    摘要: 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.

    摘要: 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. A molar ratio of the element X to Mo contained in the sulfurization-resistant layer preferably satisfies X/(Mo+X)>about 0.5. A thickness (initial thickness) of the sulfurization-resistant layer before being exposed to sulfurizing atmosphere is preferably about 3 to about 200 nm.

    摘要: 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.
