HP licenses technology to Xtreme Energetics for solar energy system

HP and Xtreme Energetics (XE), a solar energy system developer based in Livermore, Calif., have announced that they have entered into an agreement for the development of a solar energy system designed to generate electricity at twice the efficiency and half the cost of traditional solar panels.
Under the technology collaboration and licensing agreement, HP will license its inorganic transparent transistor technology, already licensed to Inpria, to XE in return for royalty payments.
The transparent transistor technology that will be used in XE's solar energy device was co-developed by HP and Oregon State University. The technology includes thin film transparent transistors, which are made from low-cost, readily available materials such as zinc and tin. The materials raise no environmental concerns and allow for higher mobility, better chemical stability and easier manufacture.
The transistor technology enables control of XE's concentration and tracking system as it provides a transparent electronic mechanism to maximize the concentration of light. When coupled with XE's system, the technology improves conversion efficiency as maximum light can get through without being blocked by traditional non-transparent electronics.
"Blending art and science, our ultra-high efficiency solar energy systems can serve both the central utility and rooftop markets using low-cost, ecologically harmonious and architecturally inspiring designs," said Colin P. Williams, chief executive officer, Xtreme Energetics. "Our agreement with HP allows us to bring an advanced solar energy solution to the market that is superior to other offerings currently available."
The flat design of XE's system eliminates the need for mechanical tracking of the sun as it traverses the sky. Also, with HP's transparent electronics technology, the system can be artistically patterned to mimic the appearance of any building material or terrain for aesthetic appeal. This low-profile design also overcomes the persistent dilemmas of mechanical solar trackers, which cast shadows onto themselves, require large maintenance costs and are vulnerable to high winds, making rooftop installations especially difficult.
"Open innovation to foster collaborative research is essential in today's fast-paced, innovation-fueled market," said Joe Beyers, vice president, Intellectual Property Licensing, HP. "Through our collaborative research and by licensing HP's core intellectual property in electronics, we are accelerating the pace of technology transfer so that it can be applied more rapidly into creating commercial, renewable energy solutions."
Transparent transistor technology is just one example from HP's portfolio of technologies available for licensing. The collection also includes assets relating to fuel cells, projectors and digital pen and paper. A complete list of technologies offered through HP's intellectual property licensing program is available at
Xtreme Energetics plans to make its solution available to commercial customers as well as the central utility market. The company also is currently seeking investment for further product development and to establish national and international manufacturing, sales and marketing teams.
HP encourages other organizations worldwide to leverage its vast research and development network and portfolio of nearly 30,000 patents to bring new technologies to market through intellectual property licensing agreements. These agreements also enable HP to generate a return on its research and development investment through licensing fees and royalties.
