SolarWindow Technologies, Inc.

WNDW·OTC·Energy & Transportation·CIK 0001071840

SolarWindow Technologies, Inc., effective March 9, 2015, is a pre-revenue company developing proprietary transparent electricity-generating coatings and application methods, referred to as "LiquidElectricity® Coatings." These coatings generate electricity by harvesting light energy from natural sun, artificial light, and low, shaded, or reflected light conditions. The company applies ultra-thin layers of LiquidElectricity® Coatings to rigid glass, and flexible glass and plastic surfaces, transforming them into organic photovoltaic devices (solar cells or modules). LiquidElectricity® is a chemical framework utilizing different ultra-thin layers, including hole transport layers, active layers, electron transport layers, and conductive contact points for electricity transmission. SolarWindow Technologies has developed expertise in each layer to optimize power, optical clarity, manufacturability, and stability. The flexibility of the LiquidElectricity® framework allows the company to target off-grid energy solutions across multiple industries, including architectural, automotive, agrivoltaic (agricultural greenhouse), aerospace, commercial transportation, and marine. LiquidElectricity® Coatings are under development at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) through a Cooperative Research and Development Agreement (CRADA). SolarWindow® also receives support from commercial contract firms specializing in chemistry, coatings processes, equipment, and manufacturing. The company's commercial development efforts include seeking technology, product licensing, and joint venture arrangements. A near-term product iteration involves the electrification of glass surfaces. When applied to glass using proprietary processes, LiquidElectricity® could be fabricated into electricity-generating windows for potential use in skylights for recreational vehicles and marine vessels, and architectural glass in new construction and retrofit applications for commercial buildings.
