See-through solar glass window developed

SolarWindow transparent solar cells enable see-through glass power generation, harvesting natural and artificial light via organic PV, spray-applied coatings, and BIPV design, outperforming thin-film modules and conventional solar by up to 10x.

New Energy Technologies, Inc. is pleased to announce that researchers developing its proprietary SolarWindow technology have achieved major scientific and technical breakthroughs, allowing the company to unveil a working prototype of the world's first-ever glass window capable of generating electricity in the upcoming weeks.

Until now, solar panels have remained opaque, with the prospect of creating a see-through glass window capable of generating electricity limited by the use of metals and various expensive processes which block visibility and prevent light from passing through glass surfaces.

Recent advances in light-trapping solar design further improve transparency and efficiency.

New Energy's ability to generate electricity on see-through glass is made possible by making use of the world's smallest working organic solar cells technology, developed by Dr. Xiaomei Jiang at the University of South Florida. Unlike conventional solar systems, New Energy's solar cells generate electricity from both natural and artificial light sources, outperforming today's commercial solar and thin-film technologies by as much as 10-fold.

New Energy's SolarWindow technology is 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.

"We're always keen to see innovations in our laboratories turn into meaningful commercial products," stated Valerie McDevitt, Assistant Vice President for Research, Division of Patents and Licensing, University of South Florida. "We very much look forward to the commercial development of New Energy's SolarWindow technology, which, if successful, could literally transform the way in which we view the use of solar energy for our homes, offices, and commercial buildings."

The University of South Florida Research Foundation has licensed Dr. Xiaomei Jiang's groundbreaking discovery and important commercial processes and applications to New Energy Solar Corporation, a wholly-owned subsidiary of New Energy Technologies, Inc.

"It's very exciting to see that our ongoing research has led to several significant breakthroughs with transparency and the production of electricity on see-thru glass," explained Mr. Meetesh V. Patel, President and CEO of New Energy Technologies, Inc.

"For the first time ever, these advances have allowed us to develop an early-scale working prototype of the technology, which I very much look forward to unveiling in the upcoming weeks."

In recent months, numerous technical milestones have been surpassed by researchers developing New Energy's see-through SolarWindow coatings, including:

• The use of the world's smallest functional solar cells, measuring less than 1/4 the size of a grain of rice, and shown to successfully produce electricity in a published peer-reviewed study in the Journal of Renewable and Sustainable Energy of the American Institute of Physics. Importantly, these cells generate electricity from both natural and artificial light sources, outperforming today's commercial solar and thin-film technologies by as much as 10-fold

• Development of a novel, patent-pending process to spray spray-on solar coatings onto see-thru glass using commercially available technologies

• The ability to spray SolarWindow coatings onto glass at room temperature, supporting flexible solar cells manufacturing approaches and eliminating expensive high-temperature or high-vacuum production methods commonly used by current solar manufacturers.
