Overview

Vacuum thermal evaporation improves light-emitting diodes' efficiency in perovskite materials, suggesting enhanced manufacturability.

Key Points

  • The goal is to improve the efficiency of thermally evaporated perovskite light-emitting diodes using specific material modifications.
  • Utilized vacuum thermal evaporation for fabricating quasi-2D perovskite LEDs.
  • Adjusted the formamidinium precursor ratio during deposition for better phase distribution.
  • Implemented defect passivation with triphenylphosphine oxide to enhance film quality.
  • Achieved a photoluminescence quantum yield of 86.1%.
  • Demonstrated an external quantum efficiency of 19.6% for the all-evaporated PeLEDs.
  • Showed that smaller interlayer cations facilitate better carrier injection and energy transfer.
