Stable perovskite LEDs one step closer

Researchers at Linköping University, working with colleagues in Great Britain, China and the Czech Republic, have developed a perovskite light-emitting diode (LED) with both high efficiency and long operational stability. ...

Lead-halide perovskites with enhanced luminescence and stability

Lead halide perovskites are materials that emit light with a range of colors, but also suffer from poor moisture stability. Scientists in China demonstrated a new synthetic technique that can enable perovskites to emit bright ...

Perovskite solution aging: Scientists find solution

A research team from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) has proposed a new understanding of the aging process of perovskite solution and also found ...

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.
