Nanosolar Assigned Patent
(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service
ALEXANDRIA, Va., Feb. 16 -- Nanosolar, San Jose, Calif., has been assigned a patent (8,372,734) developed by Jeroen K.J. Van Duren, San Francisco, Matthew R. Robinson, San Jose, Calif., and Brian M. Sager, Menlo Park, Calif., for a "high-throughput printing of semiconductor precursor layer from chalcogenide nanoflake particles."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "Methods and devices are provided for transforming non-planar or planar precursor materials in an appropriate vehicle under the appropriate conditions to create dispersions of planar particles with stoichiometric ratios of elements equal to that of the feedstock or precursor materials, even after selective forces settling. In particular, planar particles disperse more easily, form much denser coatings (or form coatings with more interparticle contact area), and anneal into fused, dense films at a lower temperature and/or time than their counterparts made from spherical nanoparticles. These planar particles may be nanoflakes that have a high aspect ratio. The resulting dense films formed from nanoflakes are particularly useful in forming photovoltaic devices. In one embodiment, at least one set of the particles in the ink may be inter-metallic flake particles (microflake or nanoflake) containing at least one group IB-IIIA inter-metallic alloy phase."
The patent application was filed on June 19, 2007 (11/765,422). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,372,734&OS=8,372,734&RS=8,372,734
