摘要

Perovskite photodetectors have attracted intensive research interest due to promising applications in sensing, communication, and imaging. However, their performance is restricted by the narrow spectrum range, required power source, and instability in ambient environment. To address these issues, a self-powered photodetector based on the inorganic CsPbBr3 perovskite nanowire array/conjugated-polymer hybrid structure is designed. The spectra response range of the device can be extended to 950 nm, along with outstanding stability, fast response speed (111/306 mu s), and large detectivity (1.2 x 10(13) Jones). The performance parameters are comparable to or even better than most reported CsPbBr3 and conjugated-polymer photodetectors. The excellent performance is mainly attributed to the efficient carrier generation, separation, and transport resulting from array structure and favorable band structure.
