Bioelectrodes also have a big appetite for waste and are ready to be scaled up and used to clean up industrial sites while producing electricity as a byproduct
While some of today’s solar cells use a blend of cadmium and tellurium to convert light into electricity, adding the optimum amount of selenium in the right places could help increase efficiency
Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device essentially does the work of plants, converting atmospheric carbon dioxide into fuel
