Problems solved by technology

[0003] In the prior art, glass-encapsulated solar cells are generally used. This type of encapsulation mainly has the following problems: (1) The thickness of the solar cells obtained after encapsulation is relatively large. On the one hand, it is inconvenient to carry and install; on the other hand, it is difficult to apply It is used in fields with very strict weight requirements; (2) The solar cells obtained after packaging are relatively rigid, and are easily broken and damaged during installation and use

Abstract

The invention provides a flexible film solar cell packaging method and a solar cell. The solar cell comprises a backboard (5), a solar cell sheet (3) and a transparent water-vapor-resistant high-molecular film (1). One side of the solar cell sheet (3) is laminated on the backboard (5) through a first hot melt adhesive (4), and the other side of the solar cell sheet (3) is laminated on the transparent water-vapor-resistant high-molecular film (1) through a second hot melt adhesive (2). Plastic hot melt adhesives package the solar cell therein and form a complex under a certain temperature and pressure so as to protect the solar cell; a packaged solar cell is flexible, and is not easy to break and damage in installation and use processes, thereby widening the application field of a film solar module.

Description

technical field [0001] The invention belongs to the technical field of solar cell encapsulation, and in particular relates to a method for encapsulating a flexible thin-film solar cell and the solar cell. Background technique [0002] Solar cells are the core components of solar power generation systems, and also the most valuable components in solar power generation systems. [0003] In the prior art, glass-encapsulated solar cells are generally used. This type of encapsulation mainly has the following problems: (1) The thickness of the solar cell obtained after encapsulation is relatively large. On the one hand, it is inconvenient to carry and install; on the other hand, it is difficult to apply (2) The solar cells obtained after encapsulation are relatively rigid, and are easily broken and damaged during installation and use. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides a packaging method for flexible thin-fi...
