Leveraging a Stable Perovskite Composite to Satisfy Blue Electroluminescence Standards

Differential ion motion in mixed halide blue perovskite light-emitting electrochemical cells is produced with a LiPF6 salt additive, which dissociates to form electrical double layers at the electrodes and preserves the underlying perovskite structure. This combination, together with supporting electrolyte polymers, produced stable pure blue electroluminescence surpassing standard benchmarks. The background shows an edge glow rendering of the atomic force microscopy image of a blended thin film used in this study.

Pure Blue Electroluminescence: Pure Blue Electroluminescence by Differentiated Ion Motion in a Single Layer Perovskite Device

In article number 2102006, Jason D. Slinker and co-workers leverage CsPbBr3−xClx perovskites, polyelectrolytes, and a salt additive to demonstrate pure blue emission from single-layer light-emitting electrochemical cells. The electrolytes transport the ions from salt additives, enhancing charge injection and stabilizing the inherent perovskite emissive lattice for highly pure and sustained blue emission. The resulting pure blue emission meets the US NTSC blue standard benchmark.

Bright Single-Layer Perovskite Host–Ionic Guest Light-Emitting Electrochemical Cells

To achieve high performance in a simple single-layer device, a CsPbBr3 perovskite host and a novel ionic iridium complex guest were utilized along with a polyelectrolyte to demonstrate efficient light-emitting electrochemical cells. Perovskites are excellent solution-processable conductive materials, and iridium complexes continue to be of great interest as highly luminophoric materials. In light-emitting electrochemical cells, the application of a bias induces ionic redistribution that facilitates electron and hole injection and subsequent light emission.

Perovskite Light‐Emitting Electrochemical Cells: Enhanced Operational Stability of Perovskite Light‐Emitting Electrochemical Cells Leveraging Ionic Additives

Perovskite light‐emitting electrochemical cells (PeLECs) utilize ionic redistribution to emit light efficiently from single layer devices. As demonstrated by Jason D. Slinker and co‐workers in article number 2000226, PeLECs show 100 h operation in excess of 800 cd m−2 and extrapolated lifetimes of 6700 h at 100 cd m−2 with an optimal concentration of a lithium salt additive. Electrochemical impedance spectroscopy reveals lithium additives enhance efficiency through improved electrical double layer formation.

Bright and Effectual Perovskite Light-Emitting Electrochemical Cells Leveraging Ionic Additives

We leveraged a poly(ethylene oxide) electrolyte and a lithium salt in CsPbBr3 thin films to produce ~15000 cd/m2 performance in perovskite light-emitting electrochemical cells. We find that lithium salt addition reduces the occurrence of voids, charge traps, and pinholes and increases grain size and packing density. View the article.
