Effect of molybdenum/nickel sputtering on the physical and electrical conductivity of polyethylene terephthalate film and glass fibre mat

Abstract

In this paper, we introduce a novel electrode structure made of 98% molybdenum (Mo) and 2% nickel (Ni) for sputtering on polyethylene terephthalate (PET) films and glass mats. The Mo/Ni film is deposited using radio frequency (RF) magnetron sputtering. The electrical conductivity of the samples is measured using a two-point probe. X-ray diffraction, scanning electron microscopy, and atomic force microscopy are used to physically characterize the films. The results reveal that the growth structures of the Mo/Ni layer on both the PET film and the glass mat mainly affect the electrical conductivity. Pure Mo-coated PET was used as a reference sample for comparison with Mo/Ni-coated PET samples. The results may have important practical implications in flexible solar cells.
