Gold nanoparticles turn light into electrical current
19:18 February 22, 2010

Turning sunlight into electrical power is all but a new problem, but recent advancements made by researchers at the University of Pennsylvania have given a new twist to the subject. While not currently aimed at solar panel technology, their research has uncovered a way to turn optical radiation into electrical current that could lead to self-powering molecular circuits and efficient data storage.

Sending and receiving data over a wireless network is generally undertaken via radio waves. But that's not the only method. Using the optical spectrum offers the advantage of better security and blisteringly fast transfer rates to boot. Engineers from Pennsylvania State University have now succeeded in moving data outside the usual line of sight restrictions at speeds of over one gigabit per second, more than double that achieved by Siemens recently.

Researchers have developed a technique to replicate biological structures, such as butterfly wings, on a nano scale. They focused on the tiny nano-sized photonic structures that are found in the insects’ cuticle, and which give insects their iridescence - that slightly metallic sheen that also seems to shift in color depending on the viewing angle. By replicating the biotemplate of butterfly wings, the researchers hope to be able to make various optically-active structures, such as optical diffusers or coverings that maximize solar cell absorption.
