- Abstract
Time‐resolved conductivity measurements reveal that a mild hydrogen treatment at 300 °C for 10 minutes successfully extends the lifetime of carriers by more than two‐fold in bismuth vanadate (BiVO4) photoelectrodes. This enhancement is a result of passivation of deep trap states and/or reduction of their density. Consequently, the AM1.5 photocurrent and onset potential for the hydrogen‐treated BiVO4 are significantly improved. This is reported by Fatwa F. Abdi and co‐workers in article number 1701536.
