From making eco-friendly shoes to creating a new type of biofuel , algae turns out to be a pretty darn versatile material. Researchers at the U.K.’s University of Cambridge have just demonstrated another use case: a more efficient bio solar cell that’s powered by genetically modified live algae. “It’s been known for some time that photosynthetic microorganisms — single-celled algae — produce small amounts of electrons, stimulated by light, that can be harvested by electrodes to produce a current,” Professor Chris Howe , one of the lead researchers on the project, told Digital Trends. “You can think of systems based on this as a biological version of a photovoltaic cell.
