Metal halide perovskite light-emitting diodes with long-term operational stability

The project aims to develop efficient perovskite light-emitting diodes (PeLEDs) with long-term operational stability, advancing future industrialization of this promising technology.

In this project, we will incorporate ionic liquid additives into perovskites and employing novel crosslinking strategies to increase the intrinsic stability of our previously developed high-luminescence perovskite emitters.

We will further optimize the charge transport contacts to improve the charge injection balance and interfacial stability between perovskites and the interlayers.

At the core of the research is the development of stable perovskite emitters, combined with rational film optimization and device engineering.

The project proposes to combine my recent breakthrough of novel stable strategy for perovskites and our successes in achieving PeLEDs with high efficiencies, aiming to address the key challenge facing the industrialization of PeLEDs, i.e. the long-term operational stability.

Successful implementation of this project would not only accelerate the transformation of this promising technology into economic viability but also strengthen the position of Sweden as a global leader in energy-efficient technologies.

In addition, the developed novel technologies on stabilizing perovskite materials and device structures can be conveniently transferred to other perovskite-based optoelectronic devices, e.g. photodetectors and solar cells, etc., further promoting their stability improvement.
