A developed polyvinyl alcohol/polyethylene glycol (PVA/PEG) blend containing different concentrations of graphene oxide GO (PVA/PEG-GO) as dialectic materials for energy storage devices was studied. 80 wt% of PVA/ 20 wt% of PEG were doped with 0.5, 1.5, and 3 wt% of graphene oxide and prepared using the solution casting technique. The electrical properties, the dielectric constant (𝜺'), dielectric loss (𝜺"), and ac conductivity (σac), in a wide range of frequencies, were extensively investigated. The GO strongly enhanced the dielectric constant (energy storage) of the produced PVA/PEG blend, while a little variation was observed in dielectric loss (energy loss). A higher frequency shift was observed in the loss tangent peak, reflecting an augmentation in the mobility speed of the ions, causing a longer relaxation time. In response to the electric field, the charge carriers' mobility has a short range. The addition of GO caused a reduction in the semicircle diameter of a Cole-Cole profile. The ac conductivity was found to obey the power law, and the ionic conduction dominates the conductivity in all the studied frequency ranges. The produced PVA/PEG-GO blends had significant energy storage characteristics, making them an excellent choice for dielectric materials in energy storage devices.

“…The research results showed that the optimization had effectively improved the efficiency and power generation capabilities of the thermoelectric generator. Kang et al [ 23 ] explored the energy impact of a heat-pipe-assisted microencapsulated-phase-change-material heat sink for a hybrid panel consisting of photovoltaic and thermoelectric generators. The study showed that the overall energy conversion efficiency of a hybrid panel can be improved by incorporating heat pipe technology and phase change materials into the design of the heat sink.…”
