New quasiparticle unveiled in room temperature semiconductors

Physicists from Switzerland and Germany have unveiled fingerprints of the long-sought particle known as the Mahan exciton in the room temperature optical response of the popular methylammonium lead halide perovskites.

Chemist develops technique to improve solar cells

A RUDN University chemist has discovered four new stable compounds that can be obtained in the reaction of iodine with methylammonium iodide—the use of these substances will allow the production of perovskite solar panels ...

Harnessing hot carriers for high efficiency solar cells

Two-dimensional solar materials may offer a way to extract more energy from sunlight. By tuning the structure of a 2-D perovskite solar material, researchers from KAUST and the Georgia Institute of Technology have shown they ...
