Solar Cells: PtCoFe Nanowire Cathodes Boost Short-Circuit Currents of Ru(II)-Based Dye-Sensitized Solar Cells to a Power Conversion Efficiency of 12.29% (Adv. Funct. Mater. 3/2018)

In article number 1703282, Shang-Wei Chou, Yun Chi, Hung-Lung Chou, Pi-Tai Chou, and co-workers describe PtCoFe nanowires with rich {111} facets exhibiting superior I−3 reduction activity in DSSCs (dye-sensitized solar cells). The PRT-22 DSSC using Pt49Co23Fe28 nanowire as cathode shows a certified power conversion efficiency of 12.0%, which surpasses the previous power conversion efficiency (PCE) record of the DSSCs using Ru(II)-based dyes.
