The transition metal oxide, vanadium oxide has been at the forefront of both fundamental and applied research due to its potential applications ranging from semiconductor, catalysis, supercapacitors and cathodic electrodes for lithium batteries. Especially, solution-processed vanadium oxide thin films are studied as efficient hole-transport interlayer in inverted photovoltaic cells. In this work, to investigate the effect of annealing treatment on the formation of vanadium oxide particles through solution process, we controlled the crystallinity via annealing treatment. The morphology of prepared vanadium oxide was measured using the Transmission electron microscope (TEM) and Scanning electron microscope (SEM). The crystal structure of vanadium oxide was determined by X-ray diffraction (XRD). For the characterization of cell performance, the current density-voltage (J-V) curve was measured by using a source measurement unit. The photocurrent was obtained under illumination from an Oriel 3A solar simulator (AM 1.5 G). |
