At a factory on the outskirts of Stockholm, a new solar battery worth thousands of euros is manufactured every six seconds.

These miniature elements of the authorship of the Exeger company are intended to revolutionize the use of everyday gadgets such as headphones, keyboards, etc., which in the long run can radically change the attitude to light and interaction with technology.
According to numerous forecasts, in the future most gadgets will work on solar batteries, which will lead to the abandonment of the use of conventional batteries. The details of the Powerfoyle technology are currently being kept under wraps.
The co-founder of the manufacturing company, Giovanni Fili, under the influence of long winter nights in Scandinavia, came to the idea that the sun – not the only source of energy. The technology of the brand headed by him will make it possible to use energy from almost any light source – solar, lunar, candle, etc.
Indoor solar panels have been around for several decades. The first solar-powered calculators appeared in the 1970s. However, these early amorphous silicon cells were characterized by low power, brittleness, and stiffness, which limited their use.
The breakthrough occurred in 1988, when specialists from the University of California managed to create dye-sensitized solar cells (the so-called DSSC), which turned out to be much more profitable from an economic point of view. Mass assembly of these flexible translucent elements soon began.
Fili, together with his partner Henrik Lindström, developed a radically new electrode material with a conductivity 1,000 times better than its predecessors. This led to the Powerfoyle solar cells, which are now being produced on a commercial scale. They, unlike traditional glass panels, do not contain silver conductors and are not sensitive to partial shading, which positively affects efficiency.
Patented Powerfoyle material is easily integrated into various products, imitating surfaces such as wood, carbon fiber , polished steel and leather, while remaining waterproof, dustproof and shockproof.
The Exeger factory located in Stockholm is able to annually “issue on-the-mountain” up to 2.5 million m². No one in Europe can boast of such productivity.
Since its opening in 2021, the Exeger enterprise has been a recognized center of innovation. According to company management estimates, by 2030 their technology will touch the lives of at least 1 billion people in one way or another.
Powerfoyle cells are already used in headphones, bicycle helmets, wireless speakers, etc. Partners of the Swedish brand are the companies “Philips”, “Adidas” etc. Apple may join them in the near future (negotiations on this matter are currently in full swing).
