CuInS2 nanostructures were  synthesized  via  a  simple  surfactant-free solvothermal  route.  In  this  synthesis,  thiosemicarbazide  and thioglycolic acid were used as sulfur sources. The effects of different parameters such as type of precursor and time on the morphology and particle  size  of  the  samples  have  been  investigated.  The nanostructures  were  characterized  by  means  of  X-ray  diffraction (XRD),  scanning  electron microscopy  (SEM),  energy-dispersive X- ray  analysis  (EDX),  Fourier  transform  infrared  (FT-IR)  and photoluminescence  (PL)  spectroscopy.  The  fill  factor  (FF),  open circuit voltage  (Voc), and  short circuit current  (Isc) were obtained by I–V characterization.
