The photosynthetic reaction center is a photovoltaic device of molecular dimensions. It uses excitation energy from sunlight to transfer an electron across the thickness of a lipid bilayer membrane, and thereby generates a charge-separated state. The potential energy stored within this state is used to prepare the various high-energy molecules which fuel the organism. The discovery that a light-driven electron transfer process is at the heart of photosynthesis has opened the door to the application of these principles to molecular electronics as well.
