Plan Developed for Solar-to-Electricity Glass Windows

These nanosilicon PV solar cells are created through a electrochemical and ultrasound process that produces identically sized (1 to 4 nanometers in diameter) highly luminescent nanoparticles of silicon that provide varying wavelengths of photoluminescence with high quantum down conversion efficiency of short wavelengths (50% to 60%). The process of producing these silicon nanoparticles is supported by 10 issued U.S. patents, 7 pending U.S. patents, 2 issued foreign counterpart patents and 19 pending foreign counterpart patents.

When thin films of silicon nanoparticles are deposited (sprayed) onto silicon substrates, ultraviolet light is absorbed and converted into electrical current. With appropriate connections, the film acts as nanosilicon PV solar cells that have the potential of converting solar radiation to electrical energy.

Octillion's R&D work involves integrating films of silicon nanoparticles on glass surfaces in order to convert solar energy coming through home and office windows into electricity, without losing significant transparency or requiring major changes in manufacturing infrastructure.

The Company's research and development work is being conducted at fully equipped research facilities located at the University of Illinois in Urbana-Champaign (UIUC) pursuant to a Sponsored Research Agreement (SRA) with UIUC.
