Abstract :
The Ge/TiO2 composite thin films are deposited on polyimide substrate by RF sputtering method. The aim of this work is to develop a flexible and affordable solar cells material using Ge/TiO2 composite thin films. The films are deposited by varying sputtering times from 30 to 60 minutes. The surface morphological and structural composition of the thin films are studied by FESEM and X-ray diffraction. FESEM image shows the distribution of elements and the cross section of Ge/TiO2 composite thin films. XRD patterns reveal the morphology structural changes from amorphous to crystalline phase with increasing sputtering time.
