ELECTRO-DEPOSITED CuInSe2 FILMS FOR FLEXIBLE OPTOELECTRONIC APPLICATIONS

[[abstract]]In this research, one-step electro-deposition was applied to fabricate CuInSe2 films on top of Polyethylene terephthalate (PET) substrate. Proper ion concentration ratios, suitable pH values, appropriate deposition time and current density will enhance the formation of the well-crystallized CuInSe2 film on top of the PET substrate. Compositions of the film were examined by energy dispersive spectrometer (EDS) analysis. Material properties were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM) images, and. Atomic force spectroscopy (AFM). Experiment results indicate that plating solution with a pH value of 1.5, current density of 0.2 or 0.3 ASD, and deposition time of 15 minutes are preferable parameters for high-quality CuInSe2 film fabrication. The flexible CuInSe2 film shows great promises for future flexible solar optoelectronic devices.[[note]]SC
