Spectroscopy and theory shed light on excitons in semiconductors

From solar panels on our roofs to the new OLED TV screens, many everyday electronic devices simply wouldn't work without the interaction between light and the materials that make up semiconductors. A new category of semiconductors ...

Physicists develop new solar cell design for better efficiency

Physicists at Paderborn University have used complex computer simulations to develop a new design for significantly more efficient solar cells than previously available. A thin layer of organic material, known as tetracene, ...

Team develops light-powered catalyst to make hydrogen

A team from the UPC and the Catalan Institute of Nanoscience and Nanotechnology (ICN2) has designed an efficient and stable photocatalyst capable of producing hydrogen directly using sunlight. The results are published in ...

Researchers boost signal amplification in perovskite nanosheets

Perovskite materials are still attracting a lot of interest in solar cell applications. Now, the nanostructures of perovskite materials are being considered as a new laser medium. Over the years, light amplification in perovskite ...
