Project description
Improving the stability and performance of perovskite light-emitting devices
Organometal halide perovskites have attracted considerable attention for display and lighting applications due to their high photoluminescence quantum efficiencies and low synthesis costs. These advantages allow them to demonstrate high power conversion efficiencies. Although considerable progress has been made in increasing the efficiency of perovskite light-emitting diodes, stability issues have impeded their commercialisation. Funded under the Marie Skłodowska-Curie Actions programme, the goal of the Stable PeLEDs project is to produce stable and efficient perovskite light-emitting diodes. The project will investigate the root causes of device degradation that could relate to Auger recombination, ion migration and Joule heating. Optimising materials, deposition processes and device structure should also help develop high-efficiency and long-life light-emitting devices.
Objective
The organometal halide perovskites as optoelectronic materials possess numerous advantages of high photoluminescence quantum efficiencies, low cost, low-temperature and large-area solution process, exhibiting great potential in display and lighting applications. Considerable progress has been made in efficiency of perovskite light-emitting diode (PeLED), but the stability issues limit its commercialization. The goal of this project is to achieve stable and efficient PeLEDs based on addressing the root causes of the degradation of device under current stress, which may be related to Auger recombination, ion migration and Joule heating. The plan is to incorporate many of the technologies first developed in the host group at the Cavendish Laboratory and my group at the Nanjing Tech University, which have been global leaders in PeLEDs development over the last few years. This project will evaluate the lifetime of PeLEDs under varying current densities and temperatures. Microscopic post-mortem examination and photophysics characterization of aged devices will be used to determine failure mechanisms. The fundamental physics-based models of degradation will be developed. Finally, the project will achieve high efficiency and long operational lifetime PeLEDs by optimization of materials, deposition process and device structure. This project involves multiple disciplines and complementary expertise. The training will broaden my knowledge on photophysics, device physics and strengthen my transferable skills. Further, it will allow the transfer of my knowledge to the host group and develop a lasting collaboration. It is expected that the implementation of this project will promote the commercialization of PeLEDs, and have long lasting benefits both for fundamental research and industry in Europe.
