Scientists develop solar window technology

Scientists developing Solar Window technology capable of generating electricity on see-thru glass windows have achieved an important research breakthrough which could result in the replacement of materials prone to breakdown and degradation.
Successful integration of the newly-discovered compounds could lead to improved efficiency, lower production costs and enhanced future commercial manufacturability of the Solar Windows developed by New Energy Technologies.
"Early-on, we focused on developing electricity-generating coatings which remain transparent and can be applied onto glass surfaces at room-temperature. These goals were successfully achieved by our researchers and publicly demonstrated late last year," explained Mr. John A. Conklin, President and CEO of New Energy Technologies, Inc. "This year, our sights are set on commercial product development targets, such as power output, efficiency, durability, reliability, cost, and manufacturability."
Researchers are also working towards the replacement of brittle and expensive materials commonly used for generating electricity on the Solar Windows with easier to handle, low-cost liquid compounds.
New Energy's replacement compounds support one of the most important functions for generating electricity on glass surfaces of Solar Windows, namely, the movement of electrons. This 'flow' of electrons (negatively charged particles) is fundamental to generating electric 'current', necessary for powering appliances and fixtures.
During ongoing development testing, these new compounds have been shown to successfully 'mobilize' the electrons necessary for generating electricity on the Solar Window prototypes. Notably, scientists have produced these solution-based compounds without the use of expensive starting materials, and have discovered methods which allow for high reproducibility.
Unlike conventional materials used for generating electricity on organic solar cells, New Energy's liquid compounds, currently under development by scientists, remain see-thru, are easy to handle, and can be applied at room temperature and without the use of high-vacuum - all important attributes to support commercial manufacturing.
New Energy's technology called Solar Window - capable of generating electricity on see-thru glass windows is currently under development for potential application in the estimated 5 million commercial buildings in America (Energy Information Administration) and more than 80 million single detached homes.
