A US-based thin-film technology developer says it has been granted a US patent for technology invented by Ashok Chaudhari and based on the work of the late Dr. Praveen Chaudhari, winner of the 1995 US Medal of Technology.
The company Solar-Tectic LLC has developed the hybrid organic/inorganic thin-film which can be grown on inexpensive substrates, such as flexible and ordinary soda-lime glass.
It has applications in various industries such as solar, displays and OLEDs.
US patent (14/571,800) titled “Hybrid organic/inorganic eutectic solar cell” discloses a growth technique that “for the first time allows for low temperature deposition of exceptionally high quality polymer/inorganic semiconductor films from a variety of materials such as silicon, and germanium on inexpensive substrates, solving an intractable problem”.
According to Solar-Tectic LLC, the thin-film growth process is “very well suited for large-scale industrial applications using common deposition processes, such as e-beam, CVD, etc.”
New York-based Solar-Tectic also plans grow thin layers of sapphire (crystalline Al2O3) on ordinary soda-lime glass or other kinds of glasses. This can be used as a substrate for deposition of single crystalline silicon for PV purposes, as well as for display applications like covers for smartphones.
