Bioelectricity Generation in a Microbial Fuel Cell with a Self-Sustainable Photocathode

(a) Potential changes of the MCCs under different circumstances (black line is when CO₂ travelled through the silicon tube and red line is when CO₂ travel through the silicon tube was blocked with a clip. The symbols of moon and sun represent dark and light conditions, resp.). (b) Power density and polarized curves of the MCCs operated under various conditions. (c) Individual cathode and anode potentials versus current density curves (black line: CO₂ travelled through the tube under light illumination; red line: CO₂ travel through the silicon tube was blocked under light illumination; blue line: CO₂ travelled through the silicon tube in the dark).
