Date Time Why perovskite solar cells tend to segregate under influence of light Solar cells made of perovskite are cheap, easy to produce, and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite cells have a love-hate-relationship with the Sun. The light that they need to generate electricity also happens to impair the quality of the cells, thus severely limiting their efficiency and stability over time. Researchers at Eindhoven University of Technology have now developed a theory that explains why compound perovskite cells are unstable in sunlight. The study was published in Nature Communications. Perovskite is an attractive alternative to silicon for solar cells because it’s abundant and easy to produce. What’s more, over the past decade, the performance of perovskite solar cells has improved dramatically, with efficiency rates reaching more than 25 percent, close to the state-of-art for silicon solar cells. ....
New Technique Helps Determine the Acidity of Molecules Written by AZoMApr 29 2021 The chemical behavior of a substance is mainly governed by its degree of acidity or alkalinity. The so-called proton affinity plays a role as a decisive factor and shows how easily an entity emits or attracts a single proton.
Using the modified tip of an atomic force microscope, individual atoms in the surface can be probed. Image Credit: TU Wien. The measurement of the proton affinity of molecules has been relatively easy than it is for surfaces. This is crucial because atoms on surfaces exhibit extremely different proton affinities, based on where they are located. ....

Kuppusamy, KIT Light can be used to operate quantum information processing systems, e.g. quantum computers, quickly and efficiently. Researchers at Karlsruhe Institute of Technology (KIT) and Chimie ParisTech/CNRS have now significantly advanced the development of molecule-based materials suitable for use as light-addressable fundamental quantum units. As they report in the journal Nature Communications, they have demonstrated for the first time the possibility of addressing nuclear spin levels of a molecular complex of europium(III) rare-earth ions with light.
