Properties of Sonochemically Prepared CuIn_xGa_1-xS₂and CuIn_xGa_1-xSe₂

Abstract

Nanoparticles of chalcopyrites copper indium gallium sulde (CuInxGa1-xS2 or CIGS) and copper indium gallium selenide (CuInxGa1-xSe2 or CIGSe) were fabricated sonochemically.They were characterized by Xray diraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, high resolution transmission electron microscopy, selected area electron diraction, and diuse reectance spectroscopy.The electrical and photoelectrical properties of the fabricated nanomaterials were investigated.
