Summary: In this study, high photoluminescence quantum yield organic-inorganic hybrid perovskite quantum dots (PeQDs) were synthesized for light-emitting applications. The PeQDs, when mixed with polydimethylsiloxane, acted as a color-conversion layer (CCL) for quantum-dot light emitting diodes (LEDs) and achieved high power efficiency. By blending the PeQDs with polyvinylcinnamate, photopatternable thin films were formulated and patterned using UV light. The resulting perovskite quantum dot-polymer nanocomposites (PQD-PNCs) showed higher PLQY and stability, suggesting their potential as effective CCLs for future micro-LEDs.

Summary: This study explores a method to achieve high efficiency and stability in semiconducting lead halide perovskite nanocrystals (PNCs) through a single processing strategy by finding suitable surface ligands. The PNC ink prepared using this method can be used to fabricate both LED and PV devices, with peak electroluminescence external quantum efficiency of 17.00% and power conversion efficiency of 14.92%. It is found that a careful design of the aromatic rings in the ligands is crucial for achieving high performance, ease of processing, and improved phase stability. This research demonstrates the role of ligand design in PNC ink formulations for high-throughput production of optoelectronic devices and paves the way for dual-mode devices with both PV and LED functionalities.
