Abstract:Modern transparent technology requires high-energy-density and long-lasting transparent energy storage devices. In this study, we deposited a V 2 O 5 /ZnO film on flexible substrates by the magnetron sputtering technique and varied its radio power from 50 to 110 W. We found that the film thickness increased from 0.85 to 1.67 μm and decreased to 1.35 μm, and transparency decreased from 78 to 70% and increased to 76% from 50 to 80 and 110 W, respectively, resulting in highly energetic secondary electrons. The V … Show more
