STRUCTURAL, OPTICAL AND ELECTRICAL CHARACTERIZATION OF BORON SUBPHTHALOCYANINE CHLORIDE THIN FILMS FOR PHOTOVOLTAIC APPLICATIONS

Abstract: In the present work thin films of Boron Subphthalocyanine Chloride (sub pc) have been prepared by thermal deposition technique. The prepared films have been structurally characterized by X-ray diffraction (XRD), atomic force microscopy (AFM) and field emission scanning electron microscopic (FESEM) studies. The optical characterization of the film has been done by UV-Vis absorption spectrophotometry and by spectroscopic ellipsometric technique. The admittance spectroscopy of the film was done over five orders of frequency range. The carrier mobility through the films has been extracted by differential susceptibility method. Further,AC and DC conductivity of the sub pc film along with key dielectric parameters are also being reported. The Transport mechanism of carriers has been found to be hopping in nature.
