Abstract
In order to investigate the photo-electric property in $VO_2$ film grown by a sol-gel method, the currents generated by the light irradiation and nonirradiation were measured as functions of the bias voltage and the temperature. From the result, the generated current in the film changed with the light irradiation and nonirradiation, and it gradually increased with the bias voltage. In particular, the maximum current was generated at $50^{\circ}C$ under the light irradiation; the temperature is lower comparing the MIT (metal-insulator transition) temperature in $VO_2$. This result indicates that $VO_2$ shows the photo-voltaic effect, and so that, it is expected that the $VO_2$ film is applied for a photo-voltaic device.
