Technical FAQs 4

What is power roll?

Power Roll has been focusing on embossing 'microgroove structures' into a plastic substrate, similar to a "hologram" on a credit card. A single square meter has 500,000 microgroove structures, and these are coated with conductive materials and photo-active ink. Layers of encapsulation film keep the printed rolls stable and enhance their durability.

What happened to power roll?

2012: Angel investors form Power Roll. The R&D team, supported by a number of academic partners, continue to develop our unique solar film. 2019 - Solar film achieves 11% PCE. Further investments in Power Roll support technical and commercial development. 2021 - international partner agreements signed.

Can power roll print low-cost solar film?

Since 2012, UK-based Power Roll has been working on a way to print low-cost solar film. It's now one crucial step closer to manufacturing its lightweight film, with a new design for its perovskite solar cells that should drop production costs.

Does power roll use perovskite?

It's inexpensive and efficient. In addition, Power Roll is going with abundant perovskite as a key material in its solar cells to absorb sunlight and convert it into electricity. The company has already been at this for a while and has loads of patents to prove it, so what's new?
