A cell for water electrolysis/fuel cell power generation which includes a flow path configured to supply or discharge water in a first direction substantially perpendicular to a stacking direction of the cell; an oxygen-containing gas flow path configured to discharge or supply an oxygen-containing gas in a second direction substantially perpendicular to the stacking direction of the cell; and a hydrogen-containing gas flow path configured to discharge or supply the hydrogen-containing gas in a third direction substantially perpendicular to the stacking direction of the cell. Each of the oxygen-side electrode layer and the hydrogen-side electrode layer is an electrode layer having water repellency.

Cell for water electrolysis/fuel cell power generation and cell stack body having a plurality of same cells stacked

A method for manufacturing a photoelectric converter, comprising: forming a first buffer layer comprising a metal sulfide on a light-absorbing layer comprising a Group I-III-VI compound or a Group I-II-IV-VI compound; and contacting a surface of the first buffer layer with a first solution comprising an alkali metal compound.

Method for manufacturing photoelectric converter

A multi-layer photoelectric conversion device and technology is disclosed. A first photoelectric converter is separated from a second photoelectric converter by an insulative layer. The photoelectric converters may be of a variety of types, and the insulative layer provides protection to reduce pinhole faults in the multi-layer photoelectric conversion device.

Combined photoelectric conversion device

A wiring board comprising an insulating substrate containing at least an organic resin, a plurality of electrically conducting wiring layers formed on the surface and/or inside of said insulting substrate, and via-hole conductors formed in said insulating substrate in order to electrically connect the plurality of electrically conducting wiring layers, wherein said via-hole conductors contain an organic binder as well as a Cu&mdash;Sn intermetallic compound as an electrically conducting component. The via-hole conductors formed in the wiring board exhibit a high electric conductivity and a large heat resistance, making it possible to very highly reliably connect the electrically conducting wiring layers together.

Wiring board

A multilayer wiring board formed by laminating a plurality of circuit board units each including an insulating board containing at least a thermosetting resin, and a wiring circuit layer formed on the surface of said insulating board, wherein said insulating board is provided with via hole conducting passages so as to electrically connect the wiring circuit layers of the neighboring circuit board units, said via hole conducting passages are formed by filling via holes formed in the insulating board with a conducting paste, and said wiring circuit layer is buried in the surface of the insulating board in a manner that said insulating board possesses a flat surface. The multilayer wiring board has a satisfactory flatness required for mounting flip chips. Besides, the insulating board and the via hole conducting passages are not infiltrated by chemicals such as etching solution or plating solution. There is no problem of defective circuit, and connection is highly reliably maintained offering advantage in realizing a highly dense wiring.
