May 11, 2021 Share Researchers are constantly thinking up new ways to improve solar cell technology. They’re figuring out what’s holding them back from achieving maximum efficiency and incorporating novel materials to enhance their performance. One of the latest in the latter is the use of carbon dots made from human hair waste sourced from a barbershop. The dots form a kind of ‘armor’ that enhances the performance of perovskites solar cells – a relatively new photovoltaic technology seen as the best candidate to deliver highly efficient solar electricity at a low cost in coming years. The cutting-edge solar technology has proven to be as effective in power conversion efficiency as monocrystalline silicon solar cells (what’s currently commercially available). Plus, they’re made with a compound that’s easily manufactured (unlike silicon cells). Another bonus is that it’s flexible, so it can be used in clothing, tents, backpacks, and any other on-the-go d
