In this work, we report a novel, to the best of our knowledge, strategy to improve the performance of UV-Vis self-powered CsPbBr3 quantum dot (QD) based photodetectors (PDs) by ligand modification and poly(3-hexylthiophene) (P3HT) embedding. Compared with those based on pure QDs, modified PDs show a shortened response time by nearly ten times, and increases of maximum responsivity and specific detectivity by nearly 45 and 97 times, respectively. Such PDs also show a high stability with 90% of the initial photocurrent being maintained even after storage in ambient air without any encapsulation for 30 days.
