Solar Research Patents Acquired

Nanosys, Inc. has signed exclusive licensing agreements for world-wide rights to a broad set of intellectual properties covering materials and technologies of nanocomposite solar cells developed by two of the world’s prominent nanotechnology centers: Lawrence Berkeley National Laboratory and Columbia University. The licensed patents cover important aspects of nanocomposite solar cells based on inorganic semiconductor nanomaterials such as nanocrystals, nanorods and nanowires.

Palo Alto, California – June 11, 2003 [] “In the development of a new industry, it’s important to control the intellectual property,” said Nanosys cofounder and Director of Business Development, Stephen Empedocles. “These broad-reaching patents cover some of the most fundamental aspects of nanocomposite solar technology based on inorganic semiconductor nanomaterials. Combined with our latest US$38 million financing and our recent partnership with Matsushita Electric Works, these licenses will help us accelerate this technology into the market.” The photovoltaic industry has been growing rapidly in recent years, but growth is still hampered by the high cost of traditional inorganic semiconductor solar cells that makes solar energy substantially more expensive than energy generated from fossil fuels, said the company. By incorporating inorganic semiconductor nanomaterials into a flexible host-matrix and using roll-to-roll processing to fabricate the final solar cell (similar to that developed for manufacturing photographic film), nanocomposite solar technology marries the high efficiency of inorganic semiconductor crystals with the processability of plastics. The company believes that once commercialized, this technology will revolutionize the photovoltaics industry by offering high efficiency, low cost and conformal solar cell modules that can be easily integrated into any location where energy is needed. Nanosys has already established its first major corporate partnership in this area with Matsushita Electric Works to jointly develop and incorporate these nanocomposite solar cells into building materials for residential and commercial facilities in Asia. Multiple other corporate partnerships in other solar markets and other areas of the world are being established as well.
