Why perovskite solar cells are so efficient

Solar cells with efficiencies above 20% and produced at low costs – perovskites make this possible. Now, researchers of Karlsruhe Institute of Technology (KIT) have gained fundamental insight into the function of perovskite ...

New discovery could improve organic solar cell performance

While there is a growing market for organic solar cells—they contain materials that are cheaper, more abundant, and more environmentally friendly than those used in typical solar panels - they also tend to be less efficient ...

Chemists obtained new compound for molecular machines

RUDN chemists and their colleagues have developed an innovative method of crystallisation to produce a new complex mercuric compound with hybrid organic and inorganic ligands and a highly unusual structure. Compounds such ...

Tiny magnetic tremors unlock exotic superconductivity

Deep within solids, individual electrons zip around on a nanoscale highway paved with atoms. For the most part, these electrons avoid one another, kept in separate lanes by their mutual repulsion. But vibrations in the atomic ...

Perovskite edges can be tuned for optoelectronic performance

In the eternal search for next generation high-efficiency solar cells and LEDs, scientists at Los Alamos National Laboratory and their partners are creating innovative 2D layered hybrid perovskites that allow greater freedom ...

Up, up and away: Chemists say 'yes,' helium can form compounds

Can helium bond with other elements to form a stable compound? Students attentive to Utah State University professor Alex Boldyrev's introductory chemistry lectures would immediately respond "no." And they'd be correct – ...
