| 英文摘要 | Artificial photosynthesis provides a way to store solar energy in chemical bonds. Achieving water splitting without an applied external potential bias provides the key to artificial photosynthetic devices. We describe here a tandem photo electrochemical cell design that combines a dye-sensitized photoelectrosynthesis cell (DSPEC) and an organic solar cell (OSC) in a photoanode for water oxidation. When combined with a Pt electrode for H-2 evolution, the electrode becomes part of a combined electrochemical cell for water splitting, 2H(2)O -> O-2 + 2H(2) , by increasing the voltage of the photoanode sufficiently to drive bias-free reduction of H+ to H-2 . The combined electrode gave a 1.5% solar conversion efficiency for water splitting with no external applied bias, providing a mimic for the tandem cell configuration of PSII in natural photosynthesis. The electrode provided sustained water splitting in the molec-ular photoelectrode with sustained photocurrent densities of 1.24 mA/cm(2) for 1 h under 1-sun illumination with no applied bias. |
