Description
Summary:(a) Represents the CV analysis and (b) represents the GCD analysis under dark and illuminated conditions. [Display omitted] •A hybrid MAPbI3/PEDOT-ZrO2 perovskedot composite was developed for enhanced stability and charge transport.•The MAPbI₃/PEDOT-ZrO₂ perovskedot achieved 0.51% increase in photo-conversion efficiency.•The MAPbI₃/PEDOT-ZrO₂ perovskedot demonstrated 96 % capacity retention after 500 cycles.•Reduced light charging time by threefold, making light-rechargeable batteries more practical. Designing flexible photo-batteries that are capable of charged directly by light is critical for improving off-grid power options. This paper presents a unique photo-battery design that uses a MAPbI3/PEDOT as the effective light-harvesting and hole-transporting layer, and zirconium oxide (ZrO2) as the channel for electrons and hole-blocking layer. The MAPbI3 perovskite material absorbs sunlight and develops charge carriers, while PEDOT helps transport holes to the anode, improving charge separation and minimizing recombination losses. ZrO2, with its strong electron mobility and great chemical stability, provides fast transport of electrons to the cathode. It also efficiently blocks holes, increasing overall charge transfer dynamics. This improved design improves photo-conversion efficiency by up to 0.51 % and has a high capacity retention rate of around 96 % after 500 cycles. This improved MAPbI3/PEDOT/ZrO2 photo-battery could decrease light charging time by three times, enabling adaptable, light-rechargeable batteries more practical for real-world applications.
