ZnO coated TiO2 photoanodes with improved electron transfer for dye sensitized solar cells — •Bo Liu1, Peter Lemmens1, Andrey Bakin2, Andreas Waag2, Aidin Lak3, Meinhard Schilling3, Winfried Daum4, and Samir Kumar Pal51IPKM, TU-BS, Braunschweig — 2IHT, TU-BS, Braunschweig, Germany — 3EMG, TU-BS, Braunschweig, Germany — 4IEPT, TU Clausthal — 5SNBC, Kolkata, India

ZnO coated TiO2 photoanodes for cost efficient dye sensitized solar cells are prepared using anodization of a metal electrode leading to an array of TiO2 nanotubes. Atomic layer deposition is used for the conformal covering by ZnO. Following hematoporphyrin sensitization the improved electron transfer is probed using time resolved fluorescence. Work supported by RTG-DFG 1953/1, Metrology for Complex Nanosystems and the Laboratory for Emerging Nanometrology, TU Braunschweig.
