 This paper investigates the effect of incorporating molybdenum disulfide, MOS2, into Ruddleston, Popper, RP, perovskite-thin films on their structural, morphological, and optical properties. It was found that the addition of MOS2 to the RP-peravskite films resulted in improved crystal structure and morphology, as well as increased light absorption and photocurrent generation. Furthermore, it was observed that the presence of MOS2 at the RP-peravskite interface enhanced the quantum confinement effects, and transport of photogenerated charge carriers from the perovskite to MOS2, due to its conduction band and multiple decay channels. As a result, the optoelectronic properties of the RP-peravskite, MOS2 hybrid-thin films were greatly improved, leading to a significant increase in the photocurrent density of the devices.
