| Summary: | Titanium dioxide has a number of applications in solar cells. In this study, TiO2 thin films were synthesized using a simple but less expensive, low temperature and large area deposition method referred to as chemical bath deposition. Their electrical and optical properties were examined at various temperatures where it was observed that the films exhibited low reflectance which increased with increase in wavelength with refractive indices of 2.2–2.5 in the visible spectra. Sheet resistivity ranged between 13.54±0.095 Ω/m to 17.27±0.209 Ω/m. They were use to fabricate photovoltaic cell which exhibited the following parameters: a short circuit current, Isc=0.002445 A, open voltage, Voc = 0.04731 V, a fill factor, FF=0.551 and an efficiency, η=0.531 %. They were recommended for diode applications.
