Hybrid heterostructures based on 2D molybdenum disulfide (MoS2) and organic materials are an emerging class of nanomaterials with modulated properties and potential applications for optoelectronic devices. In this work, we demonstrated the ability to fabricate hybrid MoS2-Poly(pyrrole-co-o-toluidine) thin film photodetectors using facile solution process at low temperature. Photodetectors with [9:1] ratio of [MoS2:P(Py-co-OT)] exhibited an appropriate performance in terms of responsivity and detectivity within a broadband of wavelengths that range from 420 to 750 nm. An excellent responsivity of 43.9 A/W along with a high detectivity of 1.98 × 1012 Jones and average response time of 0.36 s were achieved at 750 nm irradiation under light intensity of 300 μW.cm−2.
