* SolarWindow™ products are currently under development and not available for sale.
Under one year, Industry’s fastest calculated financial return.
SolarWindow™ achieves payback within one year, according to first-ever independently validated financial modeling results.
To produce the equivalent amount of energy with conventional solar systems would require at least 5-11 years for payback and at least 10-12 acres of valuable urban land.
Unlike the many acres of expensive downtown real estate required for solar array fields, SolarWindow™ systems can be installed on the readily-available vast window glass surfaces on tall towers and skyscrapers.
How is this possible? Liquid electricity.
Exponentially out-performing today’s solar photovoltaic (PV) systems is made possible when engineers apply electricity-generating SolarWindow™ coatings to glass. These see-through liquids create electricity-generating glass windows, successfully prototyped in the most aesthetically appealing colors in demand by building architects.
Engineered to outperform rooftop solar by 50-fold. Works in natural, shaded, and even indoor light.
SolarWindow™ can be applied to all four sides of tall towers, generating electricity using natural, shaded, and even artificial light. Conventional solar simply does not work in shaded areas or perform under artificial light.
The result? SolarWindow™ can outperform today’s solar by as much as 50-fold when installed on a 50 story building, according to independently validated power production calculations.
What's our secret? Look up.
Look up along the sides of any of today’s tall towers or skyscrapers and you’ll see glass. Lots of glass.
Our secret is the application of SolarWindow™ coatings to the many vast acres of window glass on a tall tower, turning an entire building into a source of clean, renewable energy.
Conventional solar systems cannot be applied in this way, and are instead limited to only a handful of square feet on congested rooftops. These very small tower rooftops are often crowded with service systems such as heating, ventilation, air conditioning, and elevators. These spaces are also expected to offer tenant-amenities such as rooftop gardens and pools, and other high-footprint features.
Traditional solar also requires direct sunlight and cannot operate in shaded areas, a key advantage for SolarWindow™ applications where all four sides of a tower becomes a clean power-generator.
Importantly, our engineers have designed and tested SolarWindow™ to generate electricity from artificial light such as the fluorescent systems found inside offices, schools, and commercial buildings. Today’s solar systems do not perform well indoors or under artificial light.
WIN FOR ENVIRONMENT:
Single Installation can avoid 2.2 million miles of CO2 vehicle pollution; 12-times more than solar.
Impressive: Deliver a calculated financial payback of under one year.
Innovative: Outperform today’s solar by as much as 50-fold.
Inspiring: Achieve 12-times the environmental benefits over solar.
Our goal is to deliver huge environmental gains, while generating clean, affordable electricity.
Can SolarWindow™ be better for our planet? Yes. In a big way.
A single installation of SolarWindow™ modules could:
- Avoid the carbon emissions produced by vehicles driving over 2.2 million miles each year, compared to today’s rooftop (PV) systems with only 180,000 miles.
- Provide the equivalent reductions in carbon emissions as 770 acres of forest, compared to today’s rooftop (PV) systems with only 20 to 70 acres.

SAFE LOW-COST MANUFACTURING:
Earth-abundant organic materials. Liquid coatings ideal for high speed production.
SolarWindow™ modules are created by applying ultra-thin layers of liquid coatings on to glass and flexible plastics. These liquid coatings produce ultra-small solar cells and form groups called ‘arrays’. Because of the family of materials we use and the way in which we architect our design, the final product is generically referred to as an ‘organic photovoltaic solar array’ (OPV).
Importantly, our liquid coatings are primarily made of hydrogen and carbon – two of the most abundant materials found in nature.
What makes our organic liquid coatings so good? Performance.
We use organic materials (polymers) which are dissolved into liquid form. We apply these liquids to surfaces such as flexible plastics and glass to produce see-through products which generate electricity.
Our approach works. Here’s how.
We avoid fabrication using raw materials which are difficult to process or cannot be turned into liquids. Applying liquid coatings on to glass surfaces makes our SolarWindow™ technology ideally suited for high speed roll-to-roll and sheet-to-sheet manufacturing. High-speed manufacturing techniques result in lower production costs.
Our methods do not require expensive high-temperature or high-vacuum production techniques inherent to conventional solar.
And, by manipulating our liquid coatings we’re able to produce a color wheel of architecturally-aesthetic varieties while remaining see-through. Traditional solar cannot be produced in this way.
When applied to glass, SolarWindow™ modules appear with a pleasant neutral-tint. They are aesthetically appealing and not disruptive to the eye, seemingly passive. SolarWindow™ modules invisibly capture energy from the sun and other light sources while quietly generating valuable electricity.
But, how does this compare to today’s solar?
In comparison to conventional crystalline and thin-film PV technologies, our SolarWindow™ coatings have numerous advantages:
- Designed to generate electricity on glass, enhancing the performance of today’s typically insulated commercial and residential windows. Traditional solar cannot be applied to glass windows.
- See-through, with high level of ‘visible light transmission.’ Traditional solar is not see-through.
- Able to generate significant electricity from natural, artificial or even shaded light. Traditional solar does not work in artificial or shaded light.
Currently available solar cells are largely made of silicon wafers, an expensive and brittle material that can limit their commercial usability.
Other newer generation, lower-cost, flexible thin film solar materials such as amorphous silicon, copper-indium-gallium-selenide, and cadmium telluride, often require high-vacuum and high-temperature production techniques, and are thick, bulky, and impossible to see through when compared to SolarWindow™.
