Popis:	In this research, we report a low-cost low-temperature hydrothermal technique for covering 3-dimensional (3-D) electrodeposited ZnO nanowall with thin layer of aggregated TiO2 nanoparticles on FTO substrate for dye-sensitized solar cell application, in a way that morphology and crystal structure of ZnO nanowalls were preserved. Comparing photovoltaic characteristics of devices with and without TiO2-coating layer, it was revealed that the 3-D ZnO/TiO2-nanostructured photoanode resulted in a 35 % cell performance improved mostly because of enhancement of short-circuit current density (J sc) and open-circuit voltage (V oc). The XRD pattern showed that 3-D ZnO nanowalls and TiO2 compose of wurtzite and anatase phases, respectively.
