US-based SolarWindow Technologies has announced the commercial launch of ElectroFlex, an ultra-thin, flexible solar product designed to generate electricity on flat and curved surfaces.

The product targets applications where conventional PV modules face limitations due to weight, rigidity, or mounting requirements.

The company describes ElectroFlex as a “peel-and-stick” solution that can be applied directly to various surfaces without frames, rigid glass, or conventional support structures. Its size and color can be customized to meet customer specifications.

The new product consists of a five-layer composite laminate measuring 0.85 mm in total thickness. The stack comprises a 0.10 mm front encapsulant, 0.16 mm high-efficiency solar cells, a 0.04 mm copper cell backing, a 0.30 mm composite laminate and a 0.25 mm rear substrate.

ElectroFlex is 0.85 mm thick and integrates interdigitated back-contact (IBC) cells with a power conversion efficiency of 24.4%, according to the manufacturer. It has a power-to-weight ratio of approximately 73 W/kg.

SolarWindow said it also supplies wiring, harnesses, electrical systems, and power-balancing components needed to integrate the product and deliver the electricity it generates.

The company is targeting applications in the transportation, marine, aerospace, architecture, agriculture, infrastructure, utility, and specialty vehicle sectors.

Potential applications include data centers and buildings, roofs of commercial trucks and fleet vehicles, curved train surfaces, and drone and aircraft structures, according to the manufacturer.

ElectroFlex is initially available to Tier 1 original equipment manufacturers (OEMs) in the United States. SolarWindow said it plans to expand sales to selected markets in North America and Asia over the coming quarters.

The company is also developing LiquidElectricity, a transparent coating designed to turn glass and plastic surfaces into electricity-generating elements. SolarWindow claims the technology, which remains under development, could generate electricity from natural and artificial light, as well as low-intensity, shaded, and reflected light.
