Solar 2.0: Natural Materials + Synthetic Materials

A ring of protein and pigments, half synthetic and half natural, can be used to quickly prototype light-harvesting antennas that absorb more sunlight than fully natural ones. Graduate student Michelle Harris and research scientist Darek Niedzwiedzki in PARC’s Ultrafast Laser Facility. The laser setup allows them to measure energy transfer steps among pigments in light-harvesting
