Abstract
In the present work, MoS2 nanospheres are synthesized via facile microwave assisted hydrothermal route and characterized by structural, optical and morphological analysis. The values of the band gap and refractive index calculated by UV-vis analysis is comparable to the corresponding values of silicon. The morphology is investigated by FESEM images which show the formation of nanospheres along with the presence of Mo and S elements as revealed by EDX. The electrochemical analysis is performed by plotting cyclic voltammograms for different scan rates which show the reversibility of the redox reaction. The linear relationship of the current with scan rate obeying Rendle Sevick equation reveals the diffusion-controlled reaction. Thus, this work confirms the possible use of the molybdenum disulfide as an alternative of the silicon in the solar cells.
