Substrate Influence

The substrate influence on the performance of WO3 photoanodes was studied up to 65 °C. The photocurrent increased with temperature and the onset potential shifted to lower potentials. The best operating conditions were: 45 °C for WO3/FTO and 55 °C for WO3/metal; the recombination rate increased for higher temperatures.
