Biosolar Cell Draws Electricity from Photosynthesis Process
HAIFA, Israel, Dec. 27, 2022 — Researchers from the Israel Institute of Technology (Technion) used a succulent plant to create a living “bio-solar cell” that runs on photosynthesis. The demonstration showed how the natural processes that take place in living plants could lead to a new source of green energy. The development yielded the first such cell to run on photosynthesis, according to the researchers. Typically, the researchers said, harvesting an electrical current from biological photosynthetic
