Hematite - an overview ScienceDirect Topics

Hematite is a representative metal oxide for visible light absorption [13–15]. It has a band gap of 1.9–2.2 eV, which covers most fractions of the visible light. Theoretically, based on this band gap energy, the maximum STC efficiency for hematite can reach 12.9% with a photocurrent of 10.5 mA/cm 2.
