Reality or fantasy—Perovskite semiconductor laser diodes

Abstract Perovskite semiconductor has emerged as a promising laser gain medium; however, it is still a challenge to fabricate electrically pumped perovskite lasers due to the insufficient electrical‐to‐optical conversion efficiency. Here, the current progress on the lasing performance of optically pumped perovskite lasers is reviewed. The advancement in the control of carrier transport and recombination properties of perovskite light‐emitting diode architectures is also studied. Hence, the obstacles preventing the fabrication of perovskite laser diodes are investigated. More importantly, a strategy toward electrically driven perovskite lasers is proposed base on the successful development of organic semiconductor laser diodes.image
