Lab builds spinach-powered solar cell
. The device is based on a protein complex, dubbed Photosystem I, which is derived from spinach cells. The challenge was to keep the complex functioning without water or salt, two necessities for plant life. The answer was found in a peptide, or protein fragment, that acts like a surfactant in detergents
