Abstract

This paper is the result of an experimental study on using zinc oxide (ZnO) as an alternative material to titanium oxide (TiO2) in the fabrication of dye sensitized solar cell (DSSC). The zinc oxide thin film was prepared using sol-gel route technique. ZnO powder was annealed separately at 250ºC and 500ºC. ZnO powder annealed at 500 ºC was found to be more effective compared to the one annealed at 250ºC. Higher temperature annealing condition has given significant result in producing higher grade ZnO with reduced impurity and increased absorption intensity. Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), Particle Size Analyzer and Energy Dispersive X-ray Spectrometry (EDS) were used to study the microstructure of the material. Fabrication of DSSC was carried out using ZnO porous, natural dye, graphite, sulphuric acid and ITO glasses. Tests were conducted using natural sunlight and the results revealed that the DSSC produced has an efficiency of 25.0%., very comparable with results from other studies. Thus, an effectual DSSC has been achieved.
