Octillion Achieves Breakthrough in Development of Transparent Windows Capable of Generating Electricity

Vancouver, BC – June 4, 2007 – Octillion Corp. (Pink Sheets: OCTL) today announced that in early models of Octillion’s transparent photovoltaic ‘NanoPower Windows’, scientists have successfully engineered and assembled a mechanically stable, see-through developmental prototype, which achieves optically active down-conversion and displays good electrical properties with no electrical shorts.

“Our ability to produce a developmental prototype which remains see-through while displaying favorable electrical properties, marks a significant breakthrough in development of a working prototype of our ‘NanoPower Windows’, capable of generating electricity from sunlight without losing significant transparency,” explained Mr. Harmel S. Rayat, President and CEO of Octillion Corp.

In developing an early model of the world’s first transparent photovoltaic windows of its kind, Octillion researchers have successfully ‘stacked’ silicon nanoparticles between ultra-thin films of metal, onto a glass substrate.  Preliminary tests have shown that this stack is mechanically stable and of even thickness.  Tests for optical characterization have demonstrated that the model is a high-quality see-through architecture, important to maintaining maximum transparency of the finished commercial product.

Key to the development of Octillion’s transparent NanoPower Windows is a proprietary spray coating of a silicon nanoparticle film, which is fluorescent and able to convert the sun’s energy into electricity.  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.  The proprietary process for spraying the particles onto glass surfaces is unique to Octillion, and is among the Company’s major research achievements.

In tests of the developmental prototype window, Octillion’s silicon nanoparticle film was able to successfully convert high energy photons into lower energy photons, thus optimizing electrical conversion by preventing high energy photons from being unnecessarily wasted through conversion into heat.

Above all, electrical characterization of the developmental prototype gave good electrical properties, with no shorts.

“These exciting new findings mark a significant breakthrough in our science, which in recent months, has developed strong momentum based on a series of solid research findings.  These successful outcomes have collectively propelled our early research program aggressively towards the product development path,” concluded Mr. Rayat.

SolarWindow Technologies, Inc. creates transparent electricity-generating liquid coatings. When applied to glass or plastics, these coatings convert passive windows and other materials into electricity generators under natural, artificial, low, shaded, and even reflected light conditions.

Our liquid coating technology has been presented to members of the U.S. Congress and received recognition in numerous industry publications. Our SolarWindow™ technology may generate 50-times the power of a conventional rooftop solar system and may achieve a one-year payback when installed on all four sides of a 50-story building, according to independently-validated power and financial modeling.

Power and Financial Model Disclaimer

The company's Proprietary Power Production & Financial Model (Power & Financial Model) uses photovoltaic (PV) modeling calculations, which 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 degrees 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.
