Correlating long-lived photogenerated hole populations with photocurrent densities in hematite water oxidation photoanodes
This paper, based upon our previous work on the mechanism on solar fuel synthesis and joint international collaborative work on photoholes fingerprint in Fe2O3 photoanode between UCL, Imperial and EPFL (Switzerland), elucidates quantitative correlation between the population of long-lived holes and the reason why the bias is necessary for photon-driven water splitting on these films. This work further strengthened the international collaboration between UCL, EPFL, the Japanese National Institute of Material Science, Imperial to optimise the performance of Fe2O3 photoanodes for water photolysis.
