Synthesis and enhancement of morphological and structural properties of zinc sulphide thin films nanoparticle for solar cell application.

Nanotechnology is one of the important technologies in recent years, which leads to great improvements in many areas of application, whether in the fields of electronics, medicine, physics and chemistry. Thin films of zinc sulfide nanoparticles were deposited onto glass substrates by thermal evaporation from crystals of ZnS NPs. The change in the morphological and structural properties of the membranes deposited in different substrates (100-200 and 300 ° C) was investigated by XRD, SEM, and AFM. The results obtained from XRD showed that the membranes are structured in a cubic zinc mixture with (111) preferential orientation. The size of the nanoparticles ranges from (8-22) nm through the study of FESEM. Also, by examining EDX, the main elements of the compound and the atomic and weight ratios were identified. AFM showed that the surface roughness increases with increasing temperature. The strong cubic structure taken as thin layers allowed us to conclude that ZnS NPs can be used as solar cells.
