In lab tests, separate sheets of nanocellulose film that had been treated with each of the additives were applied to dye-sensitized solar cells, which were then placed under a UV lamp for 1,000 hours.

Researchers at the University of Turku, Finland, investigated how to use bio-based materials to produce effective UV protection films for solar cells. The study, published in ACS Applied Optical ...
