Microbial Photovoltaic Cells
Photosynthetic microbial fuel cells (PMFC) and bio-photovoltaic cells (BPV) are two types of BES that employ at least one photosynthetic organism. In both cases, a phototroph is used at the anode to produce electrons. They differ in the source of those electrons. PMFCs utilize a sacrificial chemical fuel as the ultimate electron source (Fig. 1c). - Download [PDF]
