Researchers have so far bent over backwards to find the best way to make solar cells as efficient as possible and just when you thought this is it – this one’s the best, here comes another one, claiming the exact same thing. So let’s hear the “microscopic folds” formula out, which reclaims an efficiency of 47%!
Inspired by how leaves are displayed in nature, the technology relies on the more-curves-for-more- light-absorption principle. Regular solar cells can only deal with wavelengths up to a certain threshold, but with this technique, the spectrum end enlarges to 600%. The light hitting the curves is funneled through the material and then used almost in full.
And it really works! Tests have shown that in the process of curing layers of liquid with photographic adhesive with ultraviolet light, the speed of the curing triggered the level of tension and the profusion of the ripples. Ripples more superficial were called wrinkles, while folds was the name assigned to more inward ones. But contrary to common belief, it wasn’t a usage of folds that ensured the most efficiency – it was a mixture of both folds and wrinkles.
Researchers responsible for the discovery claim this technology replaces the use of silicon cells, which will keep your cost level flat.
