  • Metal halide perovskites are promising for solar energy harvesting, but currently prone to a large hysteresis and current instability. Here, Xu et al. show improvements in a hybrid material in which the fullerene is distributed at perovskite grain boundaries and thus passivates defects effectively.

  • Although several techniques have been reported to obtain electron-rich colloidal quantum dots, these materials usually suffer from poor stability under air exposure. It is now shown that the use of strongly bound ligands and a careful ligands-exchange strategy lead to air-stable n-type quantum dots that can be used in solar cells and chemical sensors.
