New nanosilicon photovoltaic solar cell technology could adapt home and office glass windows into ones capable of generating electricity from sunlight without losing significant transparency or requiring major changes in manufacturing infrastructure.

Vancouver, BC – November 28, 2006 – Octillion Corp. (Symbol: OCTL) is pleased to announce that its research and development initiatives are well under way for the development of a new patent-pending technology using nanosilicon photovoltaic solar cells that have the potential to convert normal home and office glass windows into ones capable of converting solar energy into electricity.

These nanosilicon photovoltaic solar cells are created through a unique 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 US patents, 7 pending US 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 photovoltaic solar cells that has the potential of converting solar radiation to electrical energy.

Our present research and development 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. Among our current research and development initiatives are:

 - Construction of a small scale prototype window coated with nanosilicon photovoltaic solar cells;
 - Testing of photovoltaic conversion in the prototype window;
 - Optimizing materials used in the prototype window;
 - Obtaining target light transmission of 70% through the prototype; and
 - Conducting a cost benefit engineering analysis.
