US SolarWindow Launches 0.85mm Flexible Solar Film

en.Wedoany.com Reported - US-based SolarWindow Technologies has announced that its ultra-thin flexible solar product, ElectroFlex, is now commercially available. Designed for applications where weight, rigidity, or installation conditions make conventional photovoltaic modules difficult to deploy, this product can be directly adhered to both flat and curved surfaces to generate electricity without the need for frames, rigid glass, or support structures. The company refers to this installation method as "peel-and-stick" and allows customers to customize the product's size and color as needed.

ElectroFlex features a five-layer composite laminated structure with a total thickness of 0.85mm. From the front, it consists of a 0.10mm encapsulant layer, a 0.16mm high-efficiency solar cell, a 0.04mm copper cell backsheet, a 0.30mm composite laminate, and a 0.25mm rear substrate.

The module integrates interdigitated back contact (IBC) cells with a power conversion efficiency of 24.4%. In terms of power-to-weight ratio, ElectroFlex achieves approximately 73W/kg, compared to an industry average of around 20W/kg for conventional modules. To facilitate system integration, SolarWindow also offers accompanying wiring, harnesses, electrical systems, and balance-of-system components for transmitting the generated power.

Target markets span industries including transportation, marine, aerospace, construction, agriculture, infrastructure, utilities, and specialty vehicles. Data centers and building rooftops, commercial truck and fleet vehicle roofs, curved train surfaces, and drone and aircraft structures are all listed by the company as potential applications.

Initial shipments of ElectroFlex are directed at Tier 1 original equipment manufacturers (OEMs) in the United States. SolarWindow plans to expand sales to selected markets in North America and Asia over the coming quarters.

SolarWindow is also advancing the development of its transparent coating product, LiquidElectricity, with the goal of enabling glass and plastic surfaces to generate power. According to the company, this in-development technology can utilize natural and artificial light, and can also generate electricity under low-light, shaded, and reflected-light conditions.
