Solar technology can replace traditional batteries

in Stockholm, a top-secret factory in the Far North produces blades with miniature solar cells that could change the way we interact with everyday technology. With a capacity to produce 2.5 million square meters of these cells every year, it is the largest factory of its kind in Europe. Giovanni Felli And Henrik Lindstromco-founders of Exigerhas developed a technology that can dispense with traditional batteries, it was reported The Independent.

These cells, known as Powerfoyle, can harvest energy from any light source, from direct sunlight to candlelight. Even under the moonlight, even if the charge is limited. Feeley compared his technology to algae found at the bottom of the ocean that make use of minimal photons: “We can make efficient use of very few photons“, declared L The Independent. Furthermore, he stated that Powerfoyle redefines our relationship with light, making it a constant and accessible resource.

Progress began with the discovery of dye-sensitized solar cells (DSSC) in 1988. Science developed at the University of California, Berkeley, allowed these cells to be commercialized. Twenty years later, Exiger achieved 1,000 times more conductivity in its materials, giving rise to Powerfoyle.

Other products powered by this technology include headphones, bicycle helmets, and wireless speakers. Nike, Philips and 3M They are among their clients, with advanced conversations as well Logitech and Apple. In Philly's words: “We have secured a contract with one of the largest suppliers of keyboards and mice in the world“.

The internal technology is not new. The first solar calculators appeared in the 1970s, but faced limitations due to their low power consumption and fragility. innovation Exiger It solves these problems, making its panels flexible, resistant to partial shading, waterproof and durable.

The Powerfoyle's durability and versatility allow it to be used under any lighting conditions. Although it limits its application to high-consumption devices such as laptops and smartphones, it can significantly extend the life of their batteries. Exeger is also exploring a solar-powered tablet case that could eliminate the need for charging for some users.

Ambient photonics, an American company, is also moving in this direction with its DSSCs. “Every advance in energy density brings us closer to a future without disposable batteriessaid Bates Marshall, co-founder and CEO of the company The Independent. Marshall highlighted that remote controls are responsible for the annual disposal of 3.1 billion disposable batteries, according to estimates SamsungThey can benefit greatly. The Korean company committed to replacing alkaline batteries with photovoltaic energy to reduce greenhouse gas emissions by 6,000 tons annually.

Another look at the signature Ambient photonics He reveals his interest in the smart home. Marshall comments that the limited lifespan of conventional batteries hinders the design of electronic products and has negative environmental consequences. Ambient's DSSC modules are already integrated into remote controls, although their application is more restricted than Powerfoyle's due to their sensitivity to heat and light.

Giovanni Felli Powerfoyle users have experienced becoming more aware of their lighting environment. “We make people realize light, because light is power“, highlights. According to him, this technology can touch the lives of a billion people by 2030.

innovation Exiger It is so advanced that the form and use of its products has not yet been fully announced. The Independent He notes that printers at the Stockholm plant are constantly producing Powerfoyles whose future applications remain largely a mystery. However, everything indicates that it will be integrated into commonly used products.

Feeley believes that this technology defines the era, and compares its potential effects to figures such as Jeff Bezos, Bill Gates, and Elon Musk, according to the magazine. Forbes. In his words: “Our grandchildren will laugh because we had cables“, anticipating an era in which human activity will no longer depend on conventional batteries.
