Abstract

There is disclosed a hybrid system for generating free energy from dam-water by integrating giant turbines with piezoelectric nanogenerators and solar cells. This three-in-one generator harnesses electrical energy from solar and mechanical energy. Strategically positioned large-scale turbines convert the kinetic energy of water flow into electrical energy. Concurrently, integrated piezoelectric nanogenerators transform mechanical stress from turbine operations into electrical energy via the piezoelectric effect. These nanogenerators function as self-charging hybrid supercapacitors (SCHSCs), featuring activated carbon (AC) electrodes and PVA-KOH-BTO electrolyte. Solar panels utilizing dye-sensitized solar cells (DSSCs) with TiO2 photoanodes, molybdenum disulfide (MoS2) counter electrodes, an iodine-based electrolyte, and dyes enhance energy conversion efficiency under varying solar conditions. The system efficiently generates electricity even under low-flow conditions, minimal sunlight, or when turbines are not operating at full capacity.
