Biophotovoltaic Energy Sources Based on Cyanobacteria

Biophotovoltaic energy sources based on photosynthetic organisms, e.g., cyanobacteria, capable of converting solar energy into electrical energy are considered. The use of the photosynthesis process as a renewable energy source for generating electrical energy is seen as a replacement for fossil fuels. The study evaluates a biofuel cell based on Synechococcus fabricated with different types of carbon electrodes. The design of a single-chamber cell with a proton-exchange membrane is developed. The demonstrated battery achieves a power density 10.3 mW/m2.
