Chalcopyrite quaternary semiconductor Cu (InxGa1âx) Se2 nanocrystals were successfully prepared via a relatively simple electrospinning route and characterized using X-ray powder diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and transmission electron microscopy (TEM). Semiconductor Cu(InxGa1âx)Se2 nanofibers were obtained for PVB/Cu(InxGa1âx)Se2 precursor at an applied voltage of 20 kV after annealing treatment at 400 °C for 6 h. The optical property of Cu (InxGa1âx) Se2 nanocrystals was also recorded by means of UV-vis absorption spectroscopy. We also report the first electrospinning synthesis of uniform chalcopyrite crystals Cu (InxGa1âx)Se2 nanofibers and demonstrate can be used to create simple thin film solar cells, with our first cells exhibiting an efficiency of 1.96% under AM1.5 illumination.
