| 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. |

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 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. 光功率强度对光电流的影响如图 8所示。图中采用额定光强值。当量光强如表1所示。对于锐钛矿薄膜，当施加较高的外电压时，越高的光功率会产生越大的光电流。但是，在较低的外电压下实验测定的光电流结果却很相似。这一测量结果与托雷斯等人的研究结果一致。他曾假设在较低的外压下，光电流由材料内部特点决定，而不是外加电压。金红石薄膜实验也得到了相似的结果。在较高的光电流条件下，铂电极表面出现气泡。当实验运行时间较长时（大于3小时），测定了体系产生的气体体积，同时采样后测试发现该气体是氢气。 |
