Supercapacitors have attracted significant attention in modern devices as a promising solution for electrical energy storage due to their remarkable capability undergo rapid charge and discharge cycles. While various materials are employed the construction of supercapacitors, carbon-based emerge predominant choice within commercial realm. In present report, our intention is develop an effective supercapacitor device derived from natural biomass. Therefore, we synthesized water soluble, monodisperse fluorescent carbon quantum dots (CQDs) turmeric leaves (Curcuma caesia) via single step hydrothermal carbonization. Further, doctor blade technique was coat layer CQDs on stainless steel substrate using PVA binder. We observed functional groups associated with QDs triggers fast diffusion ions transmission electrons conducting electrolyte thereby effectively mechanism. The based electrode exhibits exceptional performance characteristics specific capacitance 468 F/g highest density 78.6 Wh/kg, superior values reported most supercapacitors. demonstrated light dependent capacitive enhancement by depositing thin P3HT over CQDs. Moreover, CQDs-based achieves maximum power 733.2 W/kg when operated 1M KOH excellent retention about 80% even after 5000
