  • Reducing non-radiative recombination at the perovskite/electron transport layer interface remains a critical challenge for achieving efficient perovskite/TOPCon silicon tandem solar cells. Here, authors employ bilayer passivation using AlOx/PDAI2 treatment, achieving device efficiency of 31.6%.

  • The fractional quantum Hall effect (FQHE) is the quintessential collective quantum behaviour of charge carriers confined to two dimensions but it has not yet been observed in graphene, a material distinguished by the charge carriers' two-dimensional and relativistic character. Here, and in an accompanying paper, the FQHE is observed in graphene through the use of devices containing suspended graphene sheets; the results of these two papers open a door to the further elucidation of the complex physical properties of graphene.
