Weakly space-confined all-inorganic perovskites for light-emitting diodes

Metal halide perovskites are promising materials for light-emitting diodes (LEDs)1–4. Spatially confining charge carriers using nanocrystal/quantum dots5–9, low-dimensional perovskites10–13 and ultrathin perovskite layers14 have all been used to improve the external quantum efficiency of perovskite LEDs (PeLEDs). However, most strongly space-confined perovskites suffer from severe Auger recombination, ion migration and thermal instability, resul…

Rewrite Weakly space-confined all-inorganic perovskites for light-emitting

Metal halide perovskites are promising materials for light-emitting diodes (LEDs)1,2,3,4. Spatially confining charge carriers using nanocrystal/quantum dots5,6,7,8,9, low-dimensional perovskites10,11,12,13 and ultrathin perovskite layers14 have all been used to improve the external quantum efficiency of perovskite LEDs (PeLEDs). However, most strongly space-confined perovskites suffer from severe Auger recombination, ion migration and thermal in…

Researchers increased the brightness of perovskite LEDs (PeLEDs) to over 1.16 million nits and extended their lifespan to more than 180,000 hours.

Scientists build 29.5%-efficiency all-perovskite tandem solar cells

An international team of researchers used a novel interfacial treatment to improve the performance of perovskite solar cells across a range of narrow and wide bandgap single junction, tandem, and mini-module samples. An all-perovskite tandem solar cell demonstrated its use with a certified efficiency of 29.5%.An international research team led by China’s Huazhong University of Science and Technology has improved the efficiency of (Sn-Pb) single …
