Researchers investigated how to use bio-based materials to produce effective UV protection films for solar cells. The study was the first to compare how the properties of different bio-based UV ...

Here’s what you’ll learn when you read this story: Although solar power is one of our greatest green energy tools, some of the components of the solar cell are not so sustainable. A new study, aiming ...

A new study has revealed that dye extracted from red onion skins could significantly improve ultraviolet (UV) protection for solar cells. The research published on February 24 in ACS Applied Optical ...

Scientists have found that a dye made from red onion skin extract, combined with nanocellulose, offers a 99.9% protection rate against UV rays for solar cells. This bio-filter material outperforms ...

The UV filter is a great way to add a little bit of additional protection to the front of your lens, and the latest range of "Realpro" filters from Kenko have an anti-stain coating, anti-reflection ...

Smart contact lenses that change colour when exposed to sunlight could help beach-goers better determine when to seek shade or reapply sunscreen. European researchers have developed minuscule labels ...

In the picture, a film dyed with red onion skin extract and dye-sensitised solar cells. The films were placed on top of the solar cells in the study. Researchers at the University of Turku, Finland, ...
