PROVEN: stable PeROVskite opto-electrical films by interfacial ENgineering

Besides their excellent photo-electrical response, via attractive solution-processing, the emerging metal halide perovskites (MHPs) hold promise of enabling next-generation devices with better sensitivity, resolution and energy-conversion efficiency. The real-world application of MHPs is however currently limited by several instability issues associated with both the use of volatile organic compounds and the transition to optically inactive crystal phases. Recently, the Roeffaers lab has developed and patented a novel protocol based on interfacial engineering to overcome the phase stability issue that plagues the use of all-inorganic CsPbI3 perovskite. Project PROVEN aims to prototype outstanding opto-electronic devices utilizing the patented protocol, with the ultimate goal of realising fast and effective phase stabilization protocols at scale, for industrial applications. With industrial interest already clearly identified, PROVEN will bridge the gap between academic proof-of-concept and essential industrial needs, to strengthen KUL IP portfolio in this emerging technological space.
