Abstract:
A new method combined microbial fuel cell (MFC) with polycrystalline silicon solar cell (PSSC) was exploited to investigate its energy generation and its performance on the removal of hexavalent chromium (Cr(VI)). The open circuit voltage (Vocv) of MFC-PSSC could reach 3.540 V, which, to our best knowledge, was the maximum Vocv of MFC reported. The power density of MFC-PSSC was 754.4 mW·m−2 under simulated solar light irradiation, which increased by 990% compared to 76.2 mW·m−2 of a single MFC. The concentration of Cr(VI) in MFC was 17.06 mg·l−1, which was around 12.6 times higher than that in the MFC-PSSC (1.35 mg·l−1) after operation of 48 h. The concentration of chemical oxygen demand in MFC (264 mg·l−1) was around 6 times higher than that in the MFC-PSSC (44 mg·l−1) after operation of 48 h. This study would provide a new insight into the energy generation from MFC coupling with solar cells, and provide exciting opportunities for the utilization of solar energy and bio-energy.
