Abstract

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（PDs）由于其优异的光电特性，为高性能成像提供了机会。然而，由于众所周知的响应缓慢和钙钛矿传感器阵列制作复杂，基于钙钛矿pd的视频速率成像很少被报道。本文研制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、界面层钝化和载流子输运距离短的综合作用，该PD具有较快的响应速度，为0.275/0.39µs（上升/下降）。在计算成像算法的帮助下，绕过了复杂的阵列制作，并成功地演示了25帧s−1快速运动球的视频速率成像。因此，本研究可以将其称为PVC，并认为该相机为钙钛矿等新兴光电材料提供了新的应用场景。
