In this talk, our recent work of developing perovskite/polymer composites toward the realization of fully printable light-emitting diodes (LEDs) will be presented. The perovskite/polymer composites possess all the remarkable optoelectronic characteristics of pure perovskites. For instance, we have demonstrated their use for blue, green, and red LEDs. In addition, the device efficiency exceeded those of pure perovskite LEDs. The perovskite/polymer composites have shown advantages in improving the processibility and quality of the perovskite thin films and enhancing the structural stability of the perovskites, especially in highly humid fabrication environments. By embedding the perovskite crystals inside a polymer matrix, the perovskites can be less toxic and more environmentally benign than pure perovskites. At the end of the talk, other potential applications of perovskite/polymer composites will be briefly discussed.
