An ultrahigh performance MoS₂ photodetector with high photoresponsivity (1.94 × 10⁶ A W^–1) and detectivity (1.29 × 10¹² Jones) under 520 nm and 4.63 pW laser exposure is demonstrated. This photodetector is based on a methyl-ammonium lead halide perovskite/MoS₂ hybrid structure with (3-aminopropyl)triethoxysilane doping. The performance degradation caused by moisture is also minimized down to 20% by adopting a new encapsulation bilayer of octadecyltrichlorosilane/polymethyl methacrylate.
