Wu, Graphene-like 2H/1T-MoSe2 with superior full spectrum absorption: morphology and phase engineering. Sharma, MoS2/multiwalled carbon nanotubes based composite for room-temperature ammonia sensing. The cell with the MoS 2 layer that was annealed at 500 ˚C in Ar gas environment showed the highest efficiency of 11.9%. The Current–Voltage characteristics verified that the silicon solar cell conversion efficiency was enhanced by MoS 2 deposited layer. Performance of the silicon photovoltaic cells assisted by MoS 2 layers were investigated via a solar simulator. After annealing, the optical bandgap of the films decreased from 1.83 to 1.81 eV suggesting the creation of single-layer and few-layer of MoS 2 nanocrystals and because of the two exciton peaks generated by the K point in the Brillouin zone of MoS 2. Next, the relatively high transparency of the films prepared was observed through the transmission spectrum of the samples. After preparing the samples, the samples were characterized by UV–visible spectrophotometry, Photoluminescence spectroscopy (PL), Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR) and Thermogravimetric analysis (TGA) to verify their optical and structural properties. Some of the prepared samples were annealed at 500 ☌ under argon gas in the chemical vapor deposition (CVD) furnace and others in the atmospheric oven for 60 min. In this study, molybdenum disulfide (MoS 2) nanostructures were prepared on glass substrates using spray pyrolysis.
