The West Penn Power Sustainable Energy Fund (WPPSEF) announced today that it has invested $500,000 in Plextronics, the world leader in developing active layer technology that enables broad market commercialization of printed electronic devices, to accelerate the development of Plexcore™ HIL for solid state white lighting (SSL).
Plexcore HIL is an organic non-acidic, solvent-based hole injection layer for organic light emitting diodes (OLEDs). Plexcore HIL for SSL is an extension of the Plexcore HIL product line. The flexibility of the Plexcore™ platform enables the polymer design to be modified at the nano-molecular level and an ink to be formulated that optimizes the solid state lighting application. This ink when printed becomes an "active layer" which drives performance of the lighting device.
The investment by WPPSEF will allow product development in Plexcore HIL to expand and include emitters used in SSL applications. A key area of development will be improving the lifetime and efficiency of the device, two challenges to broad market commercialization.
