Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a flexible solar cell component for space, a preparation method and application thereof. Background technique [0002] High-altitude and long-endurance solar-powered drones have the advantages of high flight altitude, long working hours, wide coverage, flexible use, low operating costs, and no environmental pollution. The platform has a very broad application prospect. It uses solar radiation energy as power to continuously fly unmanned aerial vehicles at high altitudes for long periods of time. It uses photovoltaic cells to convert solar energy into electrical energy, and drives propellers to rotate through electric motors to generate flight power. During the day, solar-powered UAVs rely on solar cells laid on the surface of the body to convert absorbed solar radiation into electrical energy, maintain the operation of the power system, avionics and payloads, and...
