Exeger

What Exeger does

Exeger is a Swedish deep-tech company, founded in 2009 by Giovanni Fili and headquartered in Stockholm, that develops and manufactures Powerfoyle, a patented, dye-sensitized, flexible, silicon-free thin-film solar cell technology. Powerfoyle converts any form of light — indoor artificial light as well as outdoor sunlight — into electrical energy and is produced in fully custom sizes, shapes, textures, and graphic prints to integrate seamlessly into partner products. The technology is delivered in two platforms (Hybrid for indoor/outdoor environments such as headphones, trackers, and IoT devices; Indoor for remote controls, sensors, and electronic shelf labels) and is positioned to replace disposable batteries with maintenance-free, self-powered operation. Exeger operates two factories in Stockholm capable of producing up to 2.5 million square meters of Powerfoyle annually, and the technology is enabled by an integration stack that includes ultra-low-power ICs from EM Microelectronic (Swatch Group), ePaper displays from E Ink, and LTO batteries from Nichicon.

The company generates revenue primarily through B2B hardware sales and OEM/brand licensing arrangements with consumer electronics manufacturers, retailers, and industrial OEMs. Named commercial partners include Philips/TP Vision (A6219 self-charging headphones), Hama (solar-powered remotes), 3M (protective communications headset), Urbanista (Malibu speaker), Yecon (self-charging ePaper photo frame), Kapsch TrafficCom (Elumian light-powered tolling transponder), VusionGroup (EdgeSense digital shelf system), Agile Display Solutions (Forever Display), and Momax (self-powered locator), with new launches reported across Europe, China, and Japan. End-consumer ASPs for Powerfoyle-enabled devices cluster around €100–€130, and Exeger does not sell directly to consumers but leverages partner retail and e-commerce channels. As of 2025, Exeger remains pre-profitability, is actively raising equity and grant capital (including a €35M EIB loan, SEK 130M Swedish Energy Agency grant, and SEK 310M+ of equity raised in 2025), and has formally opened a Defence Tech business area following selection to the NATO DIANA Accelerator in December 2025.

Direct peers

• Heliatek: German company (Dresden) developing and producing flexible organic photovoltaic (OPV) films for building integration and consumer applications. Highly comparable to Exeger as a European flexible thin-film solar cell manufacturer serving similar end-markets with a B2B licensing/OEM model.
• Epishine: Swedish organic indoor photovoltaic cell developer (Linköping) targeting IoT sensors, remote controls and consumer electronics — the exact same application niche as Powerfoyle Indoor. Closest geographic and use-case peer to Exeger.
• Saule Technologies: Polish company developing inkjet-printed perovskite solar cells for IoT, BIPV and consumer products. Comparable as a European thin-film PV startup pursuing a similar B2B integration model and end-applications to Exeger, albeit on perovskite rather than DSSC chemistry.
• Oxford PV: UK-headquartered perovskite solar cell manufacturer with German production, targeting rooftop and utility-scale applications. Comparable as a European thin-film PV technology company pursuing scale commercialization of a non-silicon cell architecture.
• ARMOR solar power films: French subsidiary of the ARMOR group manufacturing flexible organic photovoltaic (OPV) films for building-integrated and consumer applications. Highly comparable to Powerfoyle in flexible thin-film cell technology and OEM distribution approach.
• Sunew: Brazilian company developing flexible organic photovoltaic films for building integration and consumer electronics. Comparable as a flexible thin-film solar cell producer using organic chemistry with a B2B/OEM commercialization model similar to Exeger.
• Dracula Technologies: French company developing organic photovoltaic cells ("LAYER" technology) specifically for IoT and low-power connected electronics. Directly comparable to Powerfoyle Indoor in targeting battery-less sensors and consumer electronics via printed OPV.

Broad incumbents

• Ricoh: Japanese multinational that pioneered dye-sensitized solar cell (DSSC) technology and has marketed DSSC products. Comparable as a DSSC technology holder, though Ricoh's broader imaging/services portfolio means Powerfoyle is not its core focus.
• Fujikura: Japanese diversified electronics company that has developed and commercialized dye-sensitized solar cells. Comparable as a DSSC technology developer, though solar cells sit within a much larger wire/cable and electronics portfolio rather than being the core business.

Emerging players

• SolarWindow Technologies: US-based developer of transparent photovoltaic coatings for windows and glass surfaces. Adjacent thin-film technology targeting a different (building-integrated) application than Exeger's consumer electronics focus, but relevant as a competing flexible thin-film PV company.
