Electroactive CTAB/PVDF composite film based photo-rechargeable hybrid power cell for clean energy generation and storage

Abstract Herein, electroactive polymer based photo-induced hybrid power cell has been developed using CTAB/PVDF composite film in a sustainable manner. First high dielectric polymer film has been prepared by doping CTAB in PVDF matrix via solution casting method. In the basic configuration of this hybrid power cell, aqueous electrolyte solution of PVA-MnO2-Eosin Y has been utilized as solar light absorber and photo-electron generator whereas the high dielectric CTAB/PVDF (~ 400) is used as dielectric separator cum storage part in a very transparent way. The cell shows maximum voltage $$\sim$$ ∼ 1.1 V with short-circuit current density ~ 7.83 mA/cm2 under ~ 110 mW/cm2 normal light illumination. The device reveal almost same performance for a long time (30 days). The high storage impact of the hybrid cell is investigated by its promising conversion efficiency $$\sim 4.48 \%$$ ∼ 4.48 % with energy density and power density $$\sim 26.9$$ ∼ 26.9 mWh/m2 and $$\sim$$ ∼ 5.5 W/m2 respectively.
