研究了由 n 型 TiO2 光阳极和 O2/OH− 氧化还原电解质体系制成的光电化学电池在不同温度下的性能。研究发现，当仅加热光电阳极室时，开路电压降低（∼2.0 mV K−1），短路电流增大（∼0.8 mA m−2 K−1）；然而，功率输出显示出小幅增加，然后又下降。该行为类似于肖特基势垒太阳能电池。当两个电极室都被加热时，功率输出随着温度的升高而增加（~0.4 mW m−2 K−1），这可以归因于对电极电化学反应速率的提高。
The performance of photoelectrochemical cells made of an n‐type TiO2 photoanode and the O2/OH− redox electrolyte system have been studied at different temperatures. It has been found that when only the photoanode compartment is heated, the open‐circuit voltage decreases (∼2.0 mV K−1) and the short‐circuit current increases (∼0.8 mA m−2 K−1); however, the power output shows a small increase and a fall thereafter. The behavior is similar to that of Schottky‐barrier solar cells. When both of the electrode compartments are heated, the power output increases with increasing temperature (∼0.4 mW m−2 K−1) and this can be attributed to the enhancement of the rate of the electrochemical reaction at the counterelectrode.
