▎ 摘　　要

NOVELTY - Multicomponent conductive adhesive barrier comprises an adhesive layer comprising a doped pressure-sensitive adhesive (PSA), and a conductive barrier layer including carbon or metal-based material. USE - Multicomponent conductive adhesive barrier for photoelectrode structure of photovoltaic cell (PEC) used for direct conversion of abundant feedstocks such as water, carbon dioxide, and nitrogen to fuels using solar energy. ADVANTAGE - The photoelectrode structure has high-efficiency, improved ability to capture and use renewable energy resources like solar energy, and improved photoelectrode performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a photoelectrode structure, which comprises: a substrate, a photoabsorbing layer, a multicomponent conductive adhesive barrier, and an electrocatalyst; and 2. a method for fabricating a photoelectrode structure, which involves: applying a photoabsorbing layer to a substrate; preparing an adhesive layer, where the adhesive layers comprises a doped pressure-sensitive adhesive (PSA), and forming a multicomponent conductive adhesive barrier by applying a conductive barrier layer to the adhesive layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a p-i-n perovskite solar cell.
