Work on the next generation of high-efficiency and high-brightness thin film light sources.

Over the past years, light emitting diodes (LEDs) have become highly efficient and economic light sources, replacing established technologies in lighting and display technology. LEDs based on hybrid perovskites can be part of the next generation of solid state light sources. Nowadays, they demonstrate external quantum efficiencies at par with well-established organic LEDs or quantum-dot LEDs. However, at high current densities their efficiency drops which is partly due to the electrical characteristics (conductivity, energetics etc.) of the charge transport/injection layers. This project aims to explore metal oxide based inorganic charge transport/injection layers for our in-house developed hybrid perovskites and characterize their performance via a series of electrical and physical techniques. The project will particularly focus on attempts to push high electrical current densities in the order of several 100 A/cm2 into the perovskite LEDs and analyze its influence on the performance parameters. A success of this project is realizing the next step towards low-cost, high-efficient and high-brightness thin film light sources, opening the window for a range of new miniaturized applications in medicine, analytics, sensors, displays and many more.
