Summary/Abstract: 
Halide perovskites have revolutionized the optoelectronic field in the last decade, especially by the outstanding performance of perovskite solar cells, based among others, in their low radiative recombination. This property, together with the bandgap tailoring possibilities of this family of materials, make them extremely appealing also for the development of perovskite light emitting diodes (PeLEDs). PeLEDs, as their solar cells counterparts, face two main limitations: the Pb content of the best performing systems, and the relatively low long-term stability under working conditions. PLEDs project will focus on the application-oriented development of strategies to increase PeLED stability, and will apply these strategies not just to high performance Pb-based PeLEDs but also to Pbfree systems, studying the influence of fundamental physical phenomena as self-trapped exciton, to the development and optimization of Pb-free PeLEDs. PLED project will apply this research to the use of PeLEDs in technological applications (agriculture, positioning, data communication…), where pulsed light rather than continuum use and lower intensities than for standard illumination applications are required, favoring the long-term stability, which will be analyzed in these particular environments.
