Abstract: Devices and methods for generating electricity utilizing a light-powered microbial fuel cell that includes a light-admitting reaction chamber containing a biological catalyst, such as a photosynthetic bacteria, in a growth medium, an anode and cathode disposed upon or within the reaction chamber, and a conductive material in electrical communication between the anode and cathode. The anode includes an oxidation catalyst, while the cathode includes a reduction catalyst that is accessible to oxygen gas. Preferably, the devices and methods utilize a single light-admitting chamber within which both cathodic and anodic reactions take place.
