Abstract: This paper reports on the feasibility of a tree-shaped hybrid nanogenerator (TSHG) made of flexible sheets of photovoltaic (PV) and piezoelectric (piezo) films for harnessing both wind and solar energy. The proposed system has been designed to produce electricity if there is any light, wind or strong rainfall. It shows how the power developed by each piezo film sheet was integrated in conjunction with its limited power output which is produced by the sporadic movement of the sheets. Regardless of its magnitude, the AC power output of each piezo film sheet was converted with a full wave bridge rectifier and then passed to a capacitor. The TSHG has an excellent performance with an open circuit voltage of 5.071 V, a short-circuit current of 1.282 mA, and a maximum power output of 3.42 mW at a loading resistance of 5 k?. Moreover, a wind driven TSHG was capable of charging a 1000 µF capacitor, which was subsequently discharged through LED lighting.
