  In recent years, hematite potential as a photoanode material for solar
hydrogen production has ignited a renewed interest in its physical and
interfacial properties, which continues to be an active field of research.
Research on hematite photoanodes provides new insights on the correlations
between electronic structure, transport properties, excited state dynamics and
charge transfer phenomena, and expands our knowledge on solar cell materials
into correlated electron systems. This research news article presents a
snapshot of selected theoretical and experimental developments linking the
electronic structure to the photoelectrochemical performance, with particular
focus on optoelectronic properties and charge carrier dynamics.
