Talk Tilte: Perovskite technologies for LEDs, photovoltaics, and detectors in flexible electronics applications
Abstract:
Organic-inorganic hybrid perovskites, with exceptional photophysical properties including long carrier lifetimes, low recombination rates, adjustable bandgaps, and high defect tolerance, have emerged as revolutionary candidates for optoelectronic devices. Despite their promise, critical challenges such as long-term stability, power conversion efficiency limits and scalable fabrication methods must be overcome to enable widespread commercialization. In this presentation, I will share our group’s latest breakthroughs in perovskite solar cells (PSCs), perovskite light emitting diodes (PeLEDs) and perovskite X-ray detectors. Key highlights include stabilizing black-phase formamidinium perovskite formation at room temperature and high humidity through design and synthesis of novel protic ionic liquid solvents, as well as regulating the rheological behavior of the perovskite inks for screen-printing perovskites. Additionally, we have explored strategies to accelerate radiative recombination through additive treatments for efficient perovskite light-emitting diodes (LED), and developed spin-coated epitaxial heterodimensional tin perovskites for LED applications. Finally, we have developed perovskite nanocrystal scintillators for improved performance in X-ray detection. These innovations help address longstanding bottlenecks in the field while unlocking new opportunities for industrialization.
