SolarWindow launches 0.85 mm-thick, self-adhesive solar film
SolarWindow has unveiled ElectroFlex, an ultra-thin, flexible, self-adhesive solar film boasting 24.4% efficiency and a mere 0.85 mm thickness. This 'peel-and-stick' solution is designed to electrify diverse surfaces, from truck roofs to aircraft, where traditional rigid panels fall short. Its innovative application and high performance make it a notable advancement in renewable energy integration, capturing Hacker News's attention for practical, cutting-edge technology.
The Lowdown
SolarWindow Technologies has announced the commercial launch of ElectroFlex, a groundbreaking ultra-thin, flexible solar product. This self-adhesive film is engineered to generate electricity on both flat and curved surfaces, addressing the limitations of conventional photovoltaic modules in weight, rigidity, and mounting requirements.
- Product Description: ElectroFlex is a 'peel-and-stick' solution, a 0.85 mm thick, five-layer composite laminate that can be directly applied without frames or rigid glass. Its size and color are customizable.
- Efficiency and Power: It integrates interdigitated back-contact (IBC) cells, achieving a 24.4% power conversion efficiency and a power-to-weight ratio of approximately 73 W/kg.
- Target Applications: The product is aimed at a wide array of sectors including transportation (commercial trucks, trains, aerospace), marine, architecture, agriculture, infrastructure, and specialty vehicles, with potential uses in data centers, buildings, and drones.
- Integrated Solutions: SolarWindow also provides necessary wiring, harnesses, electrical systems, and power-balancing components for full product integration.
- Availability: Initially available to Tier 1 original equipment manufacturers (OEMs) in the United States, with plans to expand to other North American and Asian markets.
Beyond ElectroFlex, SolarWindow is also developing LiquidElectricity, a transparent coating intended to transform glass and plastic surfaces into electricity generators, capable of harnessing various light conditions.
