Tracking the CPV Global Market: Ready to Fulfill Its Potential?

Not to be confused with Concentrating Solar Thermal Power (CSP), Concentrating Photovoltaics (CPV) systems use mirrors or lenses to focus the sun's light onto a small area of photovoltaic material. By focusing the sun's light (usually by several hundred times, but potentially by up to 1000 times) in order to reduce the amount of expensive semiconductor material that is needed to produce a usable quantity of energy, and so reduce the overall costs of the system.

Solar on Flexible Plastic

House 1
Researchers at New Energy Technologies, whose trademark SolarWindow technology is capable of generating electricity on see-through glass, said this week they have managed to generate electricity on flexible plastic using the company?s spray-on coating methods. The company said this new technology is an important step towards the development of electricity-generating window films.

The researchers sprayed New Energy?s electricity-generating coatings onto flexible, lightweight lab-scale plastic (polyethylene terephthalate or ?PET?) at room temperature and at low pressure, which they say could reduce manufacturing costs. They managed to overcome ?conventional issues with surface preparation? when preparing the PET prototype, which is crucial in order to achieve maximum strength of the coatings? bond to the surface and for more durability and longevity.

Besides, researchers were able to maintain the working ?architecture? of New Energy?s SolarWindow while achieving flexibility. The SolarWindow architecture enables important functions such as generating solar electricity on the surface of plastic and distributing electricity to the circuit.

And how would this translate into a commercial product? New Energy scientists envisage a see-through tinted window film. It?s not exactly a new idea, but it has been stymied in the past by difficulties such as temperature-specific and pressure sensitive methods (which were also expensive and cumbersome) for applying coating to plastic surfaces. The company?s flexible plastic overcomes such obstacles, they say.

With an estimated 85 million commercial buildings and homes in the U.S., New Energy believes there is huge potential for its SolarWindow technology, which is the subject of ten new patent filings.
