On Efficiency Of Hematite Iron Ore

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.

Hematite Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe 2 O 3 and has been widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
