摘要
Herein, we show that graphene can be fully utilized to function as an electrocatalyst in highly efficient photoelectrochemical water splitting. Combining a solution-processed organic photovoltaic and the state-of-the-art perovskite solar cell in a tandem architecture yields a stable short-circuit water splitting photocurrent of similar to 7.25 mA cm(-2) under 1 sun illumination. The similar to 7.25 mA cm(-2) photocurrent corresponds to a solar-to-hydrogen efficiency of 9.02%, which is the highest efficiency yet reported for water splitting based on a hybrid tandem perovskite solar cell.
