Leafy Green Power: Spinach is Key Ingredient in Solar Breakthrough

Leafy Green Power: Spinach is Key Ingredient in Solar Breakthrough

By adding the photosynthetic protein in spinach to silicon, researchers created biohybrid solar cells with much greater power output than previous designs. The Biohybrid Breakthrough Biohybrid solar cells are part biological molecule, part electrode material. “In our case, those molecules are Photosystem I proteins, which drive photosynthesis in green plants,” said Kane Jennings, professor of chemical and biomolecular engineering at Vanderbilt, who led the study with David Cliffel, an associate professor of chemistry. The research on using Photostream 1 (PS1) proteins in solar cells began over 40 years ago, when scientists discovered PS1 proteins could function even after they were removed from plants. Because PS1 converts sunlight into energy with nearly 100 percent efficiency, research groups began working with the protein in hopes of creating more efficient solar cells....
