摘要：

In this study, the optical and structural properties of solution-processed molybdenum disulfide (MoS2) thin films are explored. MoS2 is synthesized via chemical exfoliation and deposited on fused silica and silicon substrates using a spin-coating technique. The morphology and structural properties of the films are characterized using scanning electron microscopy and atomic force microscopy. Optical properties are examined through UV-vis and Raman spectroscopy. In the results, it is shown that the MoS2 thin films exhibit an indirect bandgap of 1.40 eV with over 60% absorption between 400 and 710 nm. Also, physics-based optical modeling predicts a potential current generation of 25 mA cm(-2) with full coverage of MoS2, indicating significant potential for solution-processed MoS2 as an absorber layer in optoelectronic applications.
