Engineered Nano-bio Hybrid Electronic Platform for Solar Energy Harvesting
Abstract
Bacteriorhodopsin is an optoelectric protein found in the membrane of the extremophile bacterium Halobacterium salinarum. The protein creates a charge gradient across its 6 nm thickness and, when integrated with inorganic electron generation and transport materials such as titania nanotubes, may find use in a new class of photon harvesters. Bacteriorhodopsin strongly absorbs light near the 570 nm wavelength but its photoelectric activity is now shown to increase by at least 35% when integrated with ultraviolet (UV)-scavenging quantum dots.
