The temperature has a large impact on the rate of a chemical reaction. For photoelectrochemical water splitting it has been shown that the photocurrent of a tungsten oxide anode increases by 64 % in a temperature interval of 25 to 65 °C.
Photoelectrochemical cells are usually not equipped with systems for active temperature control. This limits the reliability of measurement data, especially for long measurements under illumination (e.g., impedance spectroscopy). Insufficient comparability of materials is an obstacle for development and application of photoelectrochemical modules.
