Patented Solar Cell Technology
Powerfoyle is Exeger’s signature solar cell technology, designed to convert both natural and artificial light into usable energy for consumer electronics and other applications. It is a flexible, durable, and lightweight solar cell material that can be seamlessly integrated into various products, providing continuous power without the need for external charging. Unlike traditional solar panels, which are typically rigid and require direct sunlight to function optimally, Powerfoyle is designed to work efficiently with ambient indoor light as well, making it highly versatile.
"Powerfoyle is the world’s most adaptable solar cell. Thanks to our unique screen printing technique, our solar cell can be customized to match each product and the brand design. We improve products without compromising on design."

What Powerfoyle Does
Powerfoyle harnesses light energy from various sources, including sunlight and indoor lighting, to power devices by directly embedding the technology into the surface of the product. This enables electronics to be self-charging, providing energy independence for consumers and reducing the need for frequent recharging or battery replacement. Essentially, devices with Powerfoyle can continuously charge themselves throughout the day when exposed to light.
Key Applications
Consumer Electronics: Powerfoyle is particularly popular among consumers for electronics such as headphones, wearables, and wireless devices. For instance, companies like Urbanista and JBL have launched solar-powered headphones that utilize Powerfoyle, allowing users to charge their headphones while using them in daylight or indoor lighting.
Wearables: Smartwatches, fitness trackers, and similar wearable devices benefit from the self-charging feature, reducing the need for cables or docking stations.
IoT Devices: Powerfoyle’s ability to work with low-light conditions makes it suitable for Internet of Things (IoT) devices that often need constant, low-power energy input.
Smart Furniture & Automotive: Powerfoyle can also be integrated into non-electronic surfaces like furniture, automotive interiors, and backpacks, enabling them to power embedded sensors or charge portable devices.
Technology
Powerfoyle is based on dye-sensitized solar cell (DSSC) technology, but with unique enhancements that allow it to operate efficiently in a wider range of light conditions, including low and artificial lighting. DSSC is a third-generation solar technology known for being light, flexible, and more adaptable compared to traditional silicon-based solar cells. Exeger has further developed and refined this technology to improve its efficiency, durability, and versatility.
These cells are designed to be thin, flexible, and lightweight, which allows them to be integrated into diverse surfaces and products without adding bulk or compromising design.
"The breakthrough innovation that makes Powerfoyle a superior technology is a completely new material with 1000 times lower resistance than the conducting layer typically found in any flexible solar cell. That means much larger cells can be produced without the need for current collectors as seen in all other solar cells. This makes Powerfoyle the most customizable solar cell on the market."

Powerfoyle is designed to function in both direct sunlight and indoor environments, which greatly expands its application potential, particularly in urban or indoor settings. The material can be customized in terms of shape, size, colour, and texture, making it visually appealing and versatile for product integration.
