In this project, we propose to investigate the development of a battery-free UAV that can survive in the air and sustain long-term missions by harvesting solar energy, eliminating the need for battery recharging or replacement.
The use of PV cells as UAV's primary power source is considerably increasing. The solar cells installed into the UAV's wing will supply endless power for the UAV battery for day or night flights. Because PV cells can only produce energy during the daytime, all PVs must have a storage component, usually a battery .
Fuel cells, particularly proton exchange membranes, demonstrate high energy density, enabling long flight durations for lightweight UAVs, yet face challenges such as slow response and hydrogen storage limitations.
Thus, solar energy harvesting may directly power the propeller and realize fully self-powered UAVs. In contrast, mechanical energy harvesting is mainly used to charge low-power onboard electronic devices such as sensors and make UAVs partially self-powered.
