Abstract:
A photo fuel cell (PFC) offers an attractive way to simultaneously convert solar and biomass energy into electricity. Photocatalytic biomass oxidation on a semiconductor photoanode combined with dark electrochemical reduction of oxygen molecules on a metal cathode (usually Pt) in separated compartments is the common configuration for a PFC. Herein, we report a membrane‐free PFC based on a dual electrode, including a W‐doped BiVO 4 photoanode and polyterthiophene photocathode for solar‐stimulated biomass‐to‐electricity conversion. Air‐ and water‐soluble biomass derivatives can be directly used as reagents. The optimal device yields an open‐circuit voltage ( V OC ) of 0.62 V, a short‐circuit current density ( J SC ) of 775 μA cm −2 , and a maximum power density ( P max ) of 82 μW cm −2 with glucose as the feedstock under tandem illumination, which outperforms dual‐photoelectrode PFCs previously reported. Neither costly separating membranes nor Pt‐based catalysts are required in the proposed PFC architecture. Our work may inspire rational device designs for cost‐effective electricity generation from renewable resources.
