“…[28,44] As shown in Figure 7b, when the CsPbBr 3 perovskite contacts MoO 3 , the MoO 3 provides p-type oxygen vacancies and CsPbBr 3 provides n-type charge carriers, thus forming interfacial dipoles in the space-charge region. [45][46][47] Effective charge transfer between the interfaces induces downward bending of the CsPbBr 3 band and upward bending of the MoO 3 band. At the same time, under a certain laser irradiation power, the CsPbBr 3 perovskite absorbs light to generate photogenerated electron-hole pairs.…”

All‐inorganic lead halide perovskite CsPbBr3 has received a lot of attention in the field of optoelectronic devices due to its high absorption coefficient and photoelectric conversion efficiency. Using a heterojunction as the core of a photodetector (PD) to transform the optical signal into an electrical signal compensates for the deficiencies of using a single material. Here, a simple and efficient chemical vapor deposition (CVD) method is used to fabricate a CsPbBr3/MoO3/ITO heterojunction PD with superior photoresponse properties, including photoresponsivity of 37.209 A W−1 and detectivity of 1.64 × 1012 Jones at bias voltage of 3 V. Compared with pure CsPbBr3 perovskite, the responsivity of the PD is 3.54 times as great. As a photosensitive layer, CsPbBr3 absorbs photons and releases electrons due to its high optical absorption coefficient. The introduction of MoO3 plays a role in promoting the separation and transport of photogenerated carriers of the heterojunction structure and improves device performance. This study provides groundwork facilitating the use of CVD for in situ growth of high‐performance all‐inorganic perovskite heterostructures to realize the prospect of large‐scale production of perovskite PDs.

“…As a consequence, the best-performing devices showed the maximum EQE of 12.1%, which was the highest among CsPbI 3 PeLEDs at that time [ 270 ]. In fact, metal oxide/metal/metal oxide electrodes have been broadly studied in OLEDs owing to the high transparency and low resistance [ 271 , 272 , 273 ].…”

In recent years, impurity-doped nanocrystal light-emitting diodes (LEDs) have aroused both academic and industrial interest since they are highly promising to satisfy the increasing demand of display, lighting, and signaling technologies. Compared with undoped counterparts, impurity-doped nanocrystal LEDs have been demonstrated to possess many extraordinary characteristics including enhanced efficiency, increased luminance, reduced voltage, and prolonged stability. In this review, recent state-of-the-art concepts to achieve high-performance impurity-doped nanocrystal LEDs are summarized. Firstly, the fundamental concepts of impurity-doped nanocrystal LEDs are presented. Then, the strategies to enhance the performance of impurity-doped nanocrystal LEDs via both material design and device engineering are introduced. In particular, the emergence of three types of impurity-doped nanocrystal LEDs is comprehensively highlighted, namely impurity-doped colloidal quantum dot LEDs, impurity-doped perovskite LEDs, and impurity-doped colloidal quantum well LEDs. At last, the challenges and the opportunities to further improve the performance of impurity-doped nanocrystal LEDs are described.
