Octillion is developing a new nanosilicon photovoltaic solar cell technology could adapt glass windows into ones capable of generating electricity from sunlight, without losing significant transparency or requiring major changes in manufacturing infrastructure.
Vancouver, BC – February 7, 2007 – Octillion Corp. (Symbol: OCTL) today announced it has successfully achieved several milestones towards the realization of nanosilicon photovoltaic solar cell-based glass windows capable of generating electricity from sunlight, including:
- Developed a protocol for reliable deposition of nanofilms of metal on a glass window substrate prototype;
- Developed an electro spray system that deposits thin films of fluorescent silicon nanoparticles which allows for nanofilms of controllable average thickness, and
- Showed that the silicon nanoparticles retained their high efficiency of down conversion of UV light to the visible after being sprayed using luminescence spectroscopy, a procedure that does not compromise the optical characteristics of the nanoparticles, both in intensity and spectral distribution, a prerequisite for efficient photovoltaic conversion.
Octillion Corp, through a sponsored research agreement with the University of Illinois in Urbana-Champaign, is developing 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.
The 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.
SolarWindow Technologies, Inc. is a developer of next generation, transparent electricity-generating SolarWindow™ coatings.
SolarWindow™ coatings generate electricity on see-through glass and flexible plastics with colored tints popular to skyscraper glass. Unlike conventional systems, SolarWindow™ can be applied to all four sides of tall towers, generating electricity using natural and artificial light conditions and even shaded areas. SolarWindow™ uses organic materials, which are dissolved into liquid, ideal for low-cost high-output manufacturing; and is the subject of a patent pending technology.
The company’s Proprietary Power Production & Financial Model (Power & Financial Model) uses photovoltaic (PV) modeling calculations that are consistent with renewable energy practitioner standards for assessing, evaluating and estimating renewable energy for a PV project. The Power & Financial Model estimator takes into consideration building geographic location, solar radiation for flat-plate collectors (SolarWindow™ irradiance is derated to account for 360 degree building orientation and vertical installation), climate zone energy use and generalized skyscraper building characteristics when estimating PV power and energy production, and carbon dioxide equivalents. Actual power, energy production and carbon dioxide equivalents modeled may vary based upon building-to-building situational characteristics and varying installation methodologies.
