This paper describes a photovoltaic cell created from titania (TiO2) nonoparticles which exhibits realistic energy conversion efficiency. A simple method was proposed to synthesize TiO2 nanoparticles: hydrolysis of titanium isopropoxide (TIPS) in hexane, and then calcination under different temperatures (from 500 °C to 800 °C). The microstructure of TiO2 nanoparticles was characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Dye-sensitized solar cells (DSSCs) were prepared with the TiO2 nanoparticles and the cells performance was then evaluated. The results revealed that the calcination temperature substantially affected the phase and size of TiO2 nanoparticles and hence the efficiency of DSSCs. Anatase TiO2 nanoparticles 10 to 50 nm in diameter formed on calcination between 500 °C to 700 °C with the optimum solar cell efficiency for the 500 °C.
