"Photosynthesis is the primary form of energy production that sustains biological life on our planet. Photosynthesis is the bioelectrochemical process by which green plants, algae, and some bacteria absorb the energy of sunlight, convert it into electrochemical energy, and produce oxygen and organic compounds from carbon dioxide and water. Photosynthetic microbial fuel cells (MFCs) are a type of microbial fuel cells (MFCs) that utilize solar energy for its operations. PMFCs were originally tested in the 1960s with metal electrocatalysts and in the 1980s with artificial electron mediators in the anode chambers. With increasing concerns about sustainable energy supplies, solar-energy technologies are gaining increasing attention."-- Provided by publisher.
