Abstract

The UV component of solar light is responsible for skin cancer and a number of other skin disorders. An inexpensive and simple ultraviolet (UV) selective photodetector would be convenient to measure the UV exposure. A sealed two-electrode photoelectrochemical cell (PEC) based on a novel double-layer of nanocrystalline TiO2 has been designed and constructed as a UV-selective-sensor. The properties of the sensor, including spectral response, current-voltage characteristics, sensitivity, linearity and response time are reported. The results demonstrate the potential for the use of this low cost UV-photodetector - which does not require UV selective filters - to provide a warning of harmful solar UV-radiation levels.
