Abstract

A non-vacuum, two-step process has been used to prepare a series of nanocrystalline CuIn_1-xGa_xSe₂ (x=0, 0.25, 0.5, 0.75, 1) materials. An open-air solvothermal preparation in triethylenetetramine solvent was followed by annealing at 500 °C in a nitrogen atmosphere for 20 min. All materials have mixed clustered plate, spherical particle, and nanorod morphologies with the smallest particle diameters ranging between 20 and 40 nm. Raman spectroscopy and X-ray diffraction (XRD) confirm that indium/gallium ratio control is possible over a wide range. The solvothermal reaction step yields a mixture of chalcopyrite and Cu_2-xSe. This is converted to pure chalcopyrite product by annealing at 500 °C.
