Powerfoyle powers devices in low-light

The material is screen-printed onto flexible plastic, then laminated, and follows the principle of photosynthesis to generate and store electricity. According to company founder, Giovanni Fili the material can be used on ‘walls, cars, roofs’ making solar power accessible in numerous settings.

MORE RENEWABLE ENERGY CONTENT FROM THE ENGINEER

The company was reluctant to reveal light to power conversion per xcm² but it did say that Powerfoyle is able to generate up to 100 per cent more power than flexible amorphous silicon depending on light conditions.

“The reason is due to its high performance and that we don’t have any conductive layers blocking the photons or silverlines, which also blocks 10-15 per cent of the active surface,” said  Nicklas Jonsson, Chief Product Officer at Exeger via email.

“Powerfoyle is also not as sensitive to light angles due to the DSC cell type. Partial shading is not a problem either,” he added. “This is something that can easily kill the performance of other cells, but Powerfoyle is not made up of several connected serial cells, it simply has one big cell which is made possible due to the nanomaterial innovation at Exeger.”
