The device was constructed with black-odorous sediment as substrate and the modified carbon felt as electrode. We achieved a solar cell-microbial fuel cell new system after we inserted different rated voltage solar cells in series. The introduction of solar cells had an influence on electricity generation and sediment remediation. Several conclusions we got after a period operation: at the irradiation intensity of 53 mW·cm~(-2) on the surface of solar cells, the maximum output voltage and power density of S...
