Ultrafast Charge Carrier Recombination and Trapping in Hematite Photoanodes under Applied Bias

[Image: see text] Transient absorption spectroscopy on subpicosecond to second time scales is used to investigate photogenerated charge carrier recombination in Si-doped nanostructured hematite (α-Fe(2)O(3)) photoanodes as a function of applied bias. For unbiased hematite, this recombination exhibit...
