Plextronics Receives $340K Grant to Fund Plexcore PV Development

Apr 2007
Plextronics of Pittsburgh, a developer of active-layer technology for printed electronic devices (organic LED displays and lighting, polymer solar cells and plastic circuitry), announced it has been awarded a $340,500 grant from the Pennsylvania NanoMaterials Commercialization Center for continued development of Plexcore PV active-layer technology for organic solar cells. Plexcore PV polymer-based semiconductive inks increase solar conversion efficiency while extending the lifetime of the device. Plextronics cofounder and chief scientist Richard McCullough, dean of the Mellon College of Science at Carnegie Mellon University, invented the core polymer technology that has become the standard for organic-based solar cells. New thin-film technologies, including organic solar cells, hold the promise of being less expensive for mobile devices and less harmful to the environment by releasing no emissions, Plextronics said.


GLOSSARY
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
polymer
A material whose molecular structure consists of long chains made up by the repetition of many (usually thousands) of similar groups of atoms.
solar cell
A device for converting sunlight into electrical energy, consisting of a sandwich of P-type and N-type semiconducting wafers. A photon with sufficient energy striking the cell can dislodge an electron from an atom near the interface of the two crystal types. Electrons released in this way, collected at an electrode, can constitute an electrical current.
