摘要
En 中文
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 mu s (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.
