Problems solved by technology

[0002] Traditional solar cells are mostly packaged with glass and resin materials, and the outer frame is made of rigid materials such as metal, wood, and hard plastic. They are bulky, fragile, and inconvenient to carry. Therefore, flexible solar panels have appeared, but they have The manufacturing process of some flexible solar panels is difficult to meet the needs of the flexible solar panel manufacturing process with multi-layer polymer materials to form a protective film

Abstract

The invention discloses a flexible monocrystalline silicon solar cell manufacturing technique. The technique comprises the following steps: wafer sorting, wafer splicing, wafer welding, welding detection, low-temperature solidification of a cell and a substrate, low-temperature bonding of a front film, semi-finished product detection, high-temperature laminating, detection, trimming, wire outlet box pasting, positive and negative electrode soldering, glue pouring, assembling, top cover installation, and the like. As the technique comprises such steps as low-temperature solidification of the cell and the substrate, low-temperature bonding of the front film and high-temperature laminating, the technical steps are reasonable in design, and the manufactured products are good in sealing performance, flexibility and weatherability.

Description

technical field [0001] The invention relates to a solar power supply device, in particular to a production process of a flexible single crystal silicon solar cell. Background technique [0002] Traditional solar cells are mostly packaged with glass and resin materials, and the outer frame is made of rigid materials such as metal, wood, and hard plastic. They are bulky, fragile, and inconvenient to carry. Therefore, flexible solar panels have appeared, but they have Some flexible solar panel manufacturing processes are difficult to meet the needs of flexible solar panel manufacturing processes with multi-layer polymer materials forming a protective film. Contents of the invention [0003] The object of the present invention is to provide a flexible monocrystalline silicon solar cell production process with reasonable process steps and good sealing performance. [0004] For realizing the above object, technical solution of the present invention is: [0005] The invention i...
