Long-lived charge carriers in semiconductors are essential for effective sunlight-to-energy conversion. Still, few studies have fundamentally rationalized the charge carrier lifetimes. Now, metal-centred ligand field states of transition metal oxides have been suggested to control carrier lifetimes, akin to those for molecular photosensitizers.
