However, poor stability against moisture and oxygen in air has impeded the widespread applications and commercialization of perovskite-based semiconducting devices. Therefore, lots of recent researches have been devoted to enhancing the stability of perovskites, aiming to promote the practical applications of perovskite-based devices. In this proposal, we are targeting to exploit novel quasi-2D perovskite materials and to fabricate efficient, flexible perovskite light-emitting diodes (PeLEDs) based on our previous experience accumulated in the field of perovskite solar cells. This project is mainly divided into three parts. First, we will focus on the exploration of new quasi-2D perovskite materials by using functional organic spacers. Afterwards, we will combine these exploited perovskite materials with interface engineering to select the optimal charge-transporting layers, where the energy-level alignment between these layers will be the first guideline. After the successful demonstration of high-performance PeLEDs, we will integrate the device fabrication onto flexible substrates to realize forward-looking flexible PeLEDs.准二維鈣鈦礦材料;發光材料;發光二極體;介面工程;柔性元件;Quasi-2D perovskite; light-emitting materials; light-emitting diodes; interfacial engineering; flexible devices
