Thanks to ECW Reader Layman for the following comment.
A new Swedish company, Exeger, wins the European inventor award 2021. Their solar cell innovation transforms any form of light into electrical power.
Powerfoyle, the new unique and customizable solar cell, a patented material, has been brought to market after more than a decade of scientific research and industry development.
They already deliver their products to a number of head phone manufacturers like JBL, Adidas and Urbanista to power noise cancelling head phones. And furthermore to POC, a bicycle helmet company, and their self-powered helmet with an integrated and automatic rear light.
And there’s more to come soon.
I haven’t seen any technical data yet but Powerfoyle might allow a higher output at 5000K than normal solar cells which perhaps can reduce the risk of mismatch between the SKLed and this solar cell
