US Patent Office (USPTO) Awards Solar-Tectic LLC a Major Patent for Thin-Film Solar Cell and Semiconductor Technology



  The patent is for technology invented by the late Dr. Praveen Chaudhari, a

     recipient of the U.S. Medal of Technology and Innovation, and covers

  technology for a wide range of electronic applications including thin-film

    solar cells, LEDs, TFTs, FETs, solar inverters, and nanowire devices.

    Solar-Tectic LLC ("ST") announced today that

the United States Patent and Trademark Office (USPTO) has issued a major patent

(over 50 claims) for a wide range of technologies including the growth of

single crystal, highly textured, or large grained semiconductor films on

inexpensive substrates, such as ordinary glass.  The technologies were invented

by the late Dr. Praveen Chaudhari, winner of the 1995 U.S. Medal of Technology,

and have applications in various industries such as solar, displays and LEDs.

    US patent (12/774,465) titled "Methods of Growing Heteroepitaxial Single

Crystal or Large Grained Semiconductor Films and Devices Thereon" discloses a

modified Vapor-liquid-solid (VLS) thin-film (TF) growth technique that for the

first time allows for low temperature deposition of exceptionally high quality

semiconductor films from a variety of materials such as silicon, germanium, and

GaN, on inexpensive substrates.

    The cost-effective nanowire-like but thin-film growth process involving

eutectic alloys is very well suited for large-scale industrial applications and

can be carried out using common deposition processes currently used in various

industries, such as e-beam, CVD, etc.
