Synthesis of In₂Se₃/CuSe Composite Powder by Solvothermal Method

Abstract:

The In₂Se₃/CuSe composite powders with the size in the range of 2-8µm for solar cell were successfully synthesized via using relatively simple solvothermal method at atmospheric pressure by the reaction between InCI₃.4H₂O, CuCI₂.2H₂O and Selenious acid and hydrazine hydrate in ethylene glycol.The influences of reaction temperature, reaction time, concentration of solution on the phase and morphology of In2Se3/CuSe composite powders were investigated. The phase and morphology of the products h_{Subscript text}ave been well studied by X-ray diffraction (XRD)and scanning electron microscope (S_{Subscript text}EM) techniques.The study revealed that under the conditions of solvothermal method at atmospheric pressure, relative pure In₂Se₃ and CuSe powder were synthesized at temperatures of 160°C and 100°C respectively. The In₂Se₃/CuSe of irregular flake composite powders with the average size of 2-8µm had been obtained.The morphology of the products can be controlled by adding different kinds of surfactants such as PVP (Polyvinylpyrrolidone), CTAB (Hexadecyl trimethyl ammonium Bromide) and so on.
