Solarwindow Technologies (OTCMKTS:WNDW) (OTCMKTS:WNDW) develops and licenses transparent electricity‐generating coatings that can be applied to architectural glass and other smooth surfaces. By utilizing proprietary, solution‐based film deposition processes, the company’s products convert natural and artificial light into clean energy without significantly altering the appearance or functionality of conventional windows. This approach enables building façades, interior partitions and automotive glazing to serve as integrated power sources, helping to reduce reliance on external electrical grids.
The core technology centers on thin‐film photovoltaics based on copper indium gallium diselenide (CIGS) semiconductors, deposited from liquid inks at ambient pressures and temperatures compatible with standard glass manufacturing. SolarWindow’s transparent coatings maintain daylight transmission while generating electricity in direct sunlight, diffused daylight and even low‐light environments such as office interiors. The company’s pilot production line has demonstrated scalable throughput, and ongoing efforts focus on optimizing coating durability, energy conversion efficiency and installation methodologies to meet commercial building standards.
Founded in 2002 and headquartered in the Chicago metropolitan area, SolarWindow Technologies has pursued a series of research collaborations and demonstration projects across North America, Europe and Asia. The company’s development milestones include third‐party validation of power outputs on curved and slanted glass surfaces, field tests in urban and suburban environments, and partnerships with architectural glass fabricators. These engagements are designed to accelerate the adoption of building‐integrated photovoltaics and advance industry guidelines for transparent solar applications.
SolarWindow’s leadership team comprises professionals with deep expertise in materials science, renewable energy and building technologies. Senior executives and board members bring prior experience in scaling clean‐tech innovations from research labs to market. As the company progresses toward commercialization, its strategic initiatives include securing manufacturing alliances, enhancing product performance, and navigating regulatory pathways to support widespread deployment of power‐generating windows in commercial, residential and transportation sectors.
