Abstract
Here, a hybrid perovskite-organic photodetector was fabricated by integrating CsPbBr3 nanocrystals (NCs) with [6,6]-phenyl C71 butyric acid methyl ester (PC71BM), exhibiting remarkable optoelectronic properties in terms of photoresponsivity (1.72 A/W), detectivity (1.76 × 107 Jones), external quantum efficiency (EQE) (530%) under the illumination of 405 nm laser, and photoresponse time is shorter than 0.1 ms due to the assistance of heterojunction on the separation of photoexcitons.
