New Energy Researchers Develop Superior Spray-on Techniques for its SmartWindows™

Published on 2011-10-07. Author : SpecialChem

COLUMBIA, MD -- New Energy Technologies, Inc. announced that researchers developing and testing its SolarWindow™ technology, capable of generating electricity on see-through glass and flexible plastic, have demonstrated superior durability of their 'spray-on' methodology for applying electricity coatings - important to ensuring a commercially viable product lifecycle.

New Energy's SolarWindow™ underwent ongoing stress tests designed to determine the ability of the Company's spray-on electricity-generating coatings to withstand harsh mechanical bending. Upon completion of the tests, scientists concluded that New Energy's spray-on coatings continued to generate electricity on flexible plastic, despite being subjected to severe mechanical forces. In contrast to the Company's spray-on methodology, conventional spin-coatings methods resulted in immediate breakdown, with test devices failing when subjected to like forces.

"The favorable outcomes from these mechanical stress experiments pave the way for our SolarWindow™ technology as a practical solution for generating electricity on the windows of high-performance commercial buildings that are energy-efficient, healthy, and economical," explained Mr. John A. Conklin, President and CEO of New Energy Technologies, Inc.

Scientists conducted their latest tests of New Energy's SolarWindow™ by first applying the Company's see-through electricity generating coatings onto flexible plastic using a spray-on methodology. Unlike temperature and pressure sensitive manufacturing required in the production of other solar-photovoltaic products, New Energy's electricity-generating coatings are sprayed at room-temperature, making this a first-of-its-kind technology -- important to keeping manufacturing costs low.

Researchers then subjected the lab-scale flexible plastic SolarWindow™ to mechanical bend tests in order to determine 'flexural strength'. Bending and flexural strength testing is used to determine whether a material will break or fracture under force or pressure. New Energy's SolarWindow™ continued to generate electricity following these tests.

"Today's favorable results demonstrate the physical strength of our SolarWindow™ coatings, and are especially encouraging when considering the latest advancements to increased transparency and color of our technology, announced only a few weeks ago," said Mr. John A. Conklin.

In recent weeks, scientists successfully developed a first-ever working SolarWindow™ prototype using brand new electricity-generating coatings which lead to increased transparency and enhanced color. Researchers coated the glass surface of a working lab-scale prototype with newly-discovered, organic electricity-generating coatings comprised primarily of hydrogen and carbon. These new coatings favorably influence various electronic, electrochemical, and optical properties of SolarWindow™, essential to producing a highly transparent and aesthetically pleasing soft window tint and color.

Currently under development for eventual commercial deployment in the estimated 85 million commercial buildings and homes in America, SolarWindow™ is the world's first-of-its-kind technology capable of generating electricity on see-through glass windows.

About New Energy Technologies, Inc.

New Energy Technologies, Inc., together with its wholly owned subsidiaries, is a developer of next generation alternative and renewable energy technologies. Among the Company's technologies under development are:

  • MotionPower™ roadway systems for generating electricity by capturing the kinetic energy produced by moving vehicles - a patent-pending technology, the subject of 18 US and International patent applications. An estimated 250 million registered vehicles drive more than six billion miles on America's roadways, every day; and

  • SolarWindow™ technologies which enable see-through windows to generate electricity by 'spraying' their glass surfaces with New Energy's electricity-generating coatings - the subject of ten patent applications. These solar coatings are less than 1/10th the thickness of 'thin' films and make use of the world's smallest functional solar cells, 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.
  • Through established relationships with their various partners, they strive to identify technologies and business opportunities on the leading edge of renewable energy innovation. Unique to their business model is the use of the established infrastructure of the various organizations they deal with, saving them significant capital which would otherwise be required for such costs as land and building acquisition, equipment and capital equipment purchases, and other start up expenses. As a result, they are able to benefit from leading edge research while employing significantly less capital than conventional organizations.
