What are solar-powered unmanned aerial vehicles (UAVs)?
In the field of aviation, solar-powered unmanned aerial vehicles (UAVs) have attracted attention owing to their high-altitude cruise and the availability of renewable energy , .
Which energy supply system provides UAVs with energy during a cruise?
As shown in Fig. 1(a), the energy supply system, which includes photovoltaic and battery systems, provides the UAVs with energy during the cruise. The photovoltaic system contains photovoltaic arrays and a maximum power point tracker (MPPT).
How are solar-powered UAVs distributed?
Considering the actual situation in the flight process, the principle of energy distribution was used to distribute the energy inside the UAVs, and the energy distribution of solar-powered UAVs was optimized using a multi-objective genetic algorithm. A solution flow chart involving all models is shown in Fig. 7. Fig. 7. Model solving flow chart.
Are fuel cells a viable option for lightweight UAVs?
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.
A bifacial solar cell (BSC) is a photovoltaic solar cell that can produce electrical energy from both front and rear side. In contrast, monofacial solar cells produce electrical energy only when photons are incident on their front side. Bifacial solar cells and solar panels (devices that consist of multiple solar cells) can improve the electric energy output and modify the temporal power production p. History of the bifacial solar cellA silicon was first patented in 1946 by when working at and first publicly demonstrated at the same research institution by , , and in 1954; however, th. .
Several in-depth reviews on bifacial solar cells and their technology elements cover the current state-of-the-art. They summarize the most common BSC designs currently being marketed and then provide a review of. .
The efficiency of BSCs is usually determined by means of independent efficiency measurements of the front and rear sides under one sun. Sometimes, the BSC is characterized using its equivalent efficiency,.

A flywheel-storage power system uses a for , (see ) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage. Unlike common storage power plants, such as the
