Counter electrode electrocatalysts from one-dimensional coaxial alloy nanowires for efficient dye-sensitized solar cells

Cu@M@Pt (M = Fe, Co, Ni) NWs were synthesized by a simple galvanic displacement and employed as counter electrode (CE) catalysts for dye-sensitized solar cells (DSSCs), yielding markedly enhanced catalytic activities and therefore power conversion efficiencies in their devices.76
