SolarWindow Technologies, Inc. (WNDW) SolarWindow Technologies, Inc. focuses on creating cutting-edge coatings that generate electricity, primarily intended for integration into building windows and various glass surfaces. Their signature product, dubbed LiquidElectricity coatings, is engineered to produce power by capturing ambient light. These coatings are remarkably efficient, drawing energy from a range of sources including direct sunlight, artificial indoor illumination, and even subtle, shaded, or reflected light conditions. The company's process involves applying extremely thin layers of its LiquidElectricity technology onto diverse materials such as rigid glass, flexible glass, and plastic substrates. This innovative application effectively transforms conventional surfaces into sophisticated organic photovoltaic devices. The potential applications for these adaptable coatings are extensive, covering numerous industries like architecture, automotive manufacturing, agrivoltaics, aerospace, commercial transportation, and marine sectors. Currently, SolarWindow Technologies' LiquidElectricity coatings and related SolarWindow products are in an active development phase. This research is backed by partnerships with commercial contract firms and through collaborative research and development agreements with the U.S. Department of Energy's National Renewable Energy Laboratory. Founded in 1998, the company maintains its headquarters in Scottsdale, Arizona.

WNDW: 10-Q · periodic report
SolarWindow Technologies reported zero revenue for the third fiscal quarter ended May 31, 2026, maintaining its pre-revenue status as it develops transparent electricity-generating coatings. The company recorded a net loss of $696,406 for the quarter, compared to a loss of $540,293 in the prior-year period, primarily due to increased personnel costs and professional fees.
As of May 31, 2026, the company held $4,789,312 in cash and equivalents. Management believes current liquidity is sufficient to meet funding requirements for the next twelve months but acknowledged that additional capital will be required to commercialize its LiquidElectricity technology and continue as a going concern.
