Optical Properties of Spin‐Coated Solution Processed MoS<sub>2</sub>
In this study, the optical and structural properties of solution‐processed molybdenum disulfide (MoS 2 ) thin films are explored. MoS 2 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 MoS 2 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 MoS 2 , indicating significant potential for solution‐processed MoS 2 as an absorber layer in optoelectronic applications.
