摘要

Abstract Molybdenum diselenide thin films were deposited by chemical method. The precursor solution contains ammonium molybdate, sodium selenosulphite with hydrazine hydrate as a reducing agent. Various preparative conditions were optimized for the formation of thin films. The X-ray diffraction pattern shows that thin films have a layer-hexagonal phase. EDAX analysis shows that the films are nearly stoichiometric of Mo: Se: 1:2. Optical properties show a direct band gap nature with band gap energy 1.43 eV and having specific electrical conductivity in the order of 10~(-5) (Ωcm)~(-1). The configuration of fabricated cell is n-MoSe_2 I Nal (2 M) + I_2 (1 M) I C (graphite). The photoelectrochemical characterization of the films is carried out by studying current-voltage characterization, capacitance-voltage and power output characteristics. The fill factor and efficiency of the cell were found to be 34.22 and 1.01 % respectively.
