“…It has been theoretically shown that a single-junction solar cells (SCs) based on Cu 2 SnS 3 can have an efficiency of more than 30% [7]. Therefore, Cu 2 SnS 3 thin films have been extensively synthesized using various methods, such as magnetron sputtering [8], thermal evaporation [9], electro-deposition [10], sol-gel method [11], chemical bath deposition [12,13] and others [2,3]. To the best of our knowledge the highest efficiency values of SCs based on CTS have been achieved using vacuum methods [2,3].…”

We present the results of the study of the microstructure, X-ray diffraction and Raman scattering spectra of Cu2SnS3 (CTS) films synthesized at 500 o C by the sulfurization of SnCu stacked metal precursors with different annealing time. The results indicate that sulfurization time has a great influence on both composition and morphology of the film. It is shown that the process of formation of a single-phase CTS compound with a monoclinic structure and composition close to stoichiometry is completed for a synthesis time of 60 - 80 min. With an increase in the time of synthesis to 120 min, the preservation of the monoclinic structural modification of the material is observed, accompanied by a shift in the stoichiometric composition, namely copper enrichment, material delamination and degradation of microstructural characteristics. As a result, it was found that the most optimal conditions for the synthesis of a single-phase Cu2SnS3 compound of a monoclinic structure are the temperature 500 o С with the duration of the sulfurization process from 60 to 80 min.

Zinc oxide and metal-doped oxides are multifunctional nanomaterials used in the Nano World due to their distinctive characteristics and unique physical and chemical properties such as extraordinary chemical stability, anti-corrosion, low electrons conductivity, a broad range of radiation absorption, high photo stability, and tremendous heat resistance. To synthesize zinc oxide and Al-doped ZnO nanostructures with the inexpensive sol-gel method is our research objective, further we aimed to analyse the characterization of undoped and Al-doped ZnO nanopowder. Al-doped zinc oxide with compositional formula AlxZn1-xO (x = 0, 2, 4, 6) was synthesized using Zinc acetate dihydrate (Zn (CH3COO)2. 2H2O) as a precursor, Sodium hydroxide (NaOH) and distilled water were used as a second-hand medium for the preparation of the solution. Ethanol (CH2COOH) served as a versatile intermediate and was used as a solvent. The X-ray diffraction peaks suggest a hexagonal wurtzite crystal structure which matches with the pattern of the standard hexagonal structure of ZnO and Al-doped zinc oxide in all samples. X-ray diffraction result exhibits good crystallinity. The scanning electron microscopy images confirm the clear formation of spherical ZnO nanopowder and the change of the morphology of the nanopowder with the incorporation of the aluminium. The scanning electron microscopy results are in adjacent settlement with that estimated by the DebyeSheerer formula created on the X-ray diffraction pattern. The usual crystallite size of Aldoped zinc oxide decreases by an increase in Al concentration with capping without varying the temperature. X-ray diffraction and scanning electron microscopy with energy dispersive x-ray analysis revealed that all samples crystallize in polycrystalline nature with wurtzite lattice. The result of energy dispersive x-ray analysis characterization shows that the ZnO nanopowders with no other main adulterated phase. Extant learning ventures this as a low-cost method for the synthesis of pure and capped Al-doped ZnO for industry scale applications.
