  Engineering the buried interface in perovskite solar cells via lattice-matched electron transport layer

  Employing a lattice-matched perovskite oxide as an electron transport layer allows optimizing the buried interface in perovskite solar cells. A maximum power conversion efficiency of 25.17% is achieved. Cells with an initial power conversion efficiency of 24.4% maintain 90% efficiency after operation for 1,000 h.

  Bright colloidal quantum dot light-emitting diodes enabled by efficient chlorination

  Green light-emitting diodes with a brightness of 460,000 cd m^–2 and a low turn-on voltage of 2.5 V are enabled by the use of a chlorination treatment to provide conductive passivation of the devices.
