Abstract: Proposed is a CO2-reduction membrane electrode assembly (MEA), which is a novel MEA capable of changing a reaction condition to an alkaline condition from a problematic acidic condition unfavorable to reactions on a cathode side during catalytic reactions using a cation exchange membrane (CEM) as a separator. In addition, the MEA can reduce a hydrogen evolution reaction (HER), which is a side reaction. In addition, a method of manufacturing the MEA, and a CO2-reduction assembly including the MEA are also proposed.

Abstract: A chalcopyrite compound-based thin film in which an alkali metal is incorporated, and a method of fabricating the same are provided. The chalcopyrite compound-based thin film in which an alkali metal is incorporated may have improved film characteristics such as excellent chalcopyrite crystal characteristics and improved surface characteristics, and may exhibit improved optical characteristics by control of the distribution of constituent elements in the chalcopyrite compound layer. Accordingly, performance of a solar cell including the chalcopyrite compound-based thin film may be improved. The chalcopyrite compound-based thin film may be easily fabricated through a solution process.
