Four different films were deposited at 550{\^A} {\^A}oC under constant argon gas flow for 10, 15, 20, and 25{\^A} min, respectively. The surface morphology of these films analyzed with FE-SEM and AFM showed the presence of compact 1D rod-like structure of MoS2/Mo2S3in a homogeneous form. The average diameter of the 1D compact MoS2/Mo2S3 composite nanorod arrays was found in the range of 155{\^a}??298{\^A} nm deposited for different time durations. EDX analysis showed a consistency where the Mo-to-S ratio was approximately 3:4.5 and demonstrated the overall composition of the 1D MoS2/Mo2S3 composite nanorod arrays. The XRD analysis of the thin film indicated the presence of monoclinic Mo2S3 and rhombohedral MoS2composite system. Moreover, the photocurrent density of 20{\^A} min deposited thin film is observed to be 4{\^A} mA/cm2 with highest photosensitivity of 6.78{\^A} at the overpotential of 0.3{\^A} V vs Ag/AgCl under the simulated light intensity of 100{\^A} mW/cm2 (AM 1.5G). The electrochemical impedance spectroscopy (EIS) also showed improved charge transportation with highest lifetime of the photoexcited charges in 20{\^A} min deposited thin film in comparison to the other deposition time durations. This study provides the optimized synthesis conditions for producing molybdenum-based multisulfide nanostructures and the deposition duration for their deployment in solar-based devices.
