Perovskite photodetectors (PDs) provide opportunities for high‐performance imaging owing to their excellent optoelectronic properties. However, perovskite PD‐based video rate imaging has rarely been reported due to the well‐known slow response and complex array fabrication of perovskite sensors. In this work, a perovskite video camera (PVC) based on a fast perovskite PD combined with computational imaging algorithm is fabricated. The PD has a p‐i‐n structure of FTO/PTAA/MAPbI3/PC61BM/BCP/Au. Owing to combined effects of build‐in electric field, passivation of interface layer, and short carrier transport distance, the proposed PD demonstrates fast response speed of 0.275/0.39 µs (rise/fall). With the help of the computational imaging algorithm, complex array fabrication is bypassed, and successfully demonstrates video rate imaging of a fast‐moving ball with 25 frame s−1 using this single PD. Therefore, this study can call this PVC and believes that the camera provides a new application scenario for perovskite and other emerging optoelectronic materials.

 钙钛矿摄像机


钙钛矿光电探测器 （PD） 由于其出色的光电特性，为高性能成像提供了机会。然而，由于众所周知的钙钛矿传感器的慢响应和复杂的阵列制造，基于钙钛矿 PD 的视频速率成像很少被报道。在这项工作中，制造了一种基于快速钙钛矿 PD 结合计算成像算法的钙钛矿摄像机 （PVC）。PD 具有 FTO/PTAA/MAPbI3/PC61BM/BCP/Au 的 p-i-n 结构。由于内置电场、界面层钝化和短载流子传输距离的综合影响，所提出的 PD 表现出 0.275/0.39 μs（上升/下降）的快速响应速度。在计算成像算法的帮助下，绕过了复杂的阵列制造，并成功地演示了使用这种 PD 以 25 帧 s-1 的速度快速移动的球的视频速率成像。因此，本研究可以称之为 PVC，并认为该相机为钙钛矿和其他新兴光电材料提供了新的应用场景。
