Problems solved by technology

[0003] However, the thickness of the solar cells in the prior art is relatively large, which cannot meet the requirements of the unmanned aerial vehicle for its light power energy, and is affected by its packaging process. In the welding process, electric welding is generally used. The welding stress on the surface of the battery makes it unsuitable for the bending needs of the drone

Abstract

The embodiment of the invention discloses a solar cell, a packaging method of the solar cell, and an unmanned aerial vehicle employing the solar cell. The packaging method of the solar cell comprises the following steps of: providing solar cell plates; thinning the solar cell plates to form solar cell plates with preset thickness; welding the solar cell plates to form a solar cell string by a laser welding technology, wherein sections of solder strips and convergence strips in the solar cell string have an arc structure; embedding the solar cell string into ethyl vinyl acetate (EVA) adhesives; and forming the solar cell by a laminating process. The solar cell formed by the packaging method has light weight and high bending property, and the requirements of the unmanned aerial vehicle are met.

Description

technical field [0001] The invention relates to the technical field of solar cell manufacturing, in particular to a solar cell, a packaging method thereof, and an unmanned aerial vehicle using the solar cell. Background technique [0002] The main power of conventional drones is ordinary energy, but when performing high-altitude operations, they cannot carry a large amount of fuel due to the limitation of their load capacity, which makes them unable to perform long-term work in the air. With the development and maturity of solar cell technology, as well as people's understanding of new energy sources, the application of solar cells is becoming more and more extensive. Regardless of the application in the aviation field or in the ground power generation system, from the perspective of power generation speed, technology maturity and application fields, the development of solar cell technology is the fastest, thus invisibly promoting the development of solar cell technology. D...
