Abstract

An increasing energy demand and environmental pollution create a pressing need for clean and sustainable energy solutions. TiO2 semiconductor material is expected to play an important role in helping solve the energy crisis through effective utilization of solar energy based on photovoltaic devices. Dye-sensitized solar cells (DSSCs) are potentially lower cost alternative to inorganic silicon-based photovoltaic. In the present work, we report about the fabrication of dye-sensitized solar cell (DSSCs) from anodic TiO2 nanotubes powder, produced by potentiostatic anodization of Ti foil in 0.1 M HClO4 electrolyte, as photoanode. The counter electrode was made by electrodeposition of Pt from an aqueous solution of 5 mM H 2PtCl6 onto fluorine-doped tin oxide glass substrate (FTO-glass). The above frontside illuminated DSSCs were compared with back-side-illuminated DSSCs fabricated from anodic TiO2 NTs that were grown on the top of Ti foil as photoanode. The highest cell efficiency was 3.54 % under 100 mW/cm2 light intensity (1 sun AM 1.5 G light, J sc = 14.3 mA/cm2, Voc = 0.544 V, fill factor = 0.455). To the best of our knowledge, this is the first report on the fabrication of dye-sensitized solar cell from anodic TiO2 NTs powder. The TiO2/FTO photoanodes were characterized by FE-SEM, XRD and Uv-visible spectroscopy. The catalytic properties of Pt/FTO counter electrodes have been examined by cyclic voltammetry.
