| Figure 8 shows the influence of light power intensity on the photocurrent values. Nominal light intensity values are used in the figure. The equivalent light densities are shown in Table 1. In the case of anatase, higher light powers generated higher photocurrent values at high applied voltages. However, the measured photocurrent results are similar at low applied voltages. This observation coincides with the results of Torres et al. , who postulated that, at lower voltages, the photocurrent is controlled by the internal characteristics of the material and not by the externally applied voltage. Similar results were measured for rutile films as well. At high photocurrent conditions, the presence of gas bubbles was observed on the surfaces of the Pt electrodes. In case of long experimental runs (more than 3 h), the volume of gas generated was determined, and simple tests showed that the gas was hydrogen. |
