In this work, MgO2 NPs has been prepared in-situ onto the PVDF matrix to obtain an electroactive and high dielectric composite thin film. A simple, low-cost, solid-state integrated device utilizing the synthesized composite film as the active material is fabricated named as “self-charging photo power bank” (SPPB). The device shows notably high values of energy densities, power densities, and areal capacitances. The device also holds an appreciable long-term recycling capability and has powered electronic gadgets like LEDs and digital table clock.
