Fabrication, characterization, and data analysis of 2D perovskite for LED application

Abstract

This research investigates the degradation effects of 2D-organic inorganic halide perovskite (PEA)2PbBr4 in the working conditions of Perovskite Light-Emitting Diodes (PeLEDs) applications. Stability of (PEA)2PbBr4 is essential for the commercialization of PeLEDs to ensure the longevity of the device.

The perovskite is exposed to different conditions to simulate utilisation and degradation under real working conditions. The test environments include subjecting the 2D perovskite thin films to thermal, ambient, photo and electrical bias conditions. X-ray diffraction is used to analyse the crystal structure of the perovskite to understand its stability and degradation under those conditions. Observations indicate that (PEA)2PbBr4 has a high degree of stability; however, harsher conditions should be use in future testing to understand the limitations of the material.
