Biophotovoltaic biocells are algae-based battery alternatives developed by bio-designer Lucia Giron in collaboration with the University of Cambridge's Department of Biochemistry. The prototypes generate electricity through photosynthesis using living cyanobacteria, converting light into electrical current without relying on disposable chemical batteries. Designed to power low-energy devices, the project includes a demonstrator biocell alongside working prototypes for a clock radio and a temperature sensor, showcasing how the technology could be integrated into everyday products.
The transparent biocells expose the living algae while providing the light and gas exchange required for photosynthesis through a semi-permeable membrane and specialized electrode design. A removable outer plate enables components to be reused or recycled, while the cyanobacteria continue producing electricity throughout their lifespan.
