Problems solved by technology

Traditional rigid solar cell modules generally use PET light-transmitting film (about 200 μm thick) + EVA layer (about 500 μm thick) + monocrystalline silicon wafer or polycrystalline silicon wafer (about 180 μm thick) + TPE backlight, and its surface density is usually 2.0~ 2.5 kg/m 2 , leading to the lack of flexibility of the solar cell module, not only cannot adapt to the fit with the airfoil surface, but also has a large mass, which reduces the load of the solar aircraft and is difficult to meet the application requirements of the solar aircraft
[0004] At present, in the disclosed solar cell module manufacturing technology for solar drones, such as CN203659894 U and CN201510680597, rigid solar cells are used to prepare solar cell components. Fragmentation, components can...

Abstract

The invention discloses a flexible solar cell module and a preparation method and application thereof. The flexible solar cell module comprises a package skin and a module framework, wherein the module framework is arranged on a surface of the package skin, and the package skin outwards extend along at least one edge of the module framework to form a cladding edge. The flexible solar cell is prepared by a hot pressing integrated package process. The flexible crystalline silicon solar cell module has the following advantages of high surface attachment, excellent surface aerodynamic performance, light weight and the like, is convenient to install and has wide application in a spacecraft such as a solar powered unmanned air vehicle.

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...
