Laminating device and laminating method

Abstract

The invention discloses a laminating device and a laminating method. The laminating device comprises a laminating machine lower cavity, a laminating machine upper cavity, a vacuum pumping device and a pressure device, wherein a heating device is arranged in each of the laminating machine lower cavity and the laminating machine upper cavity; a thin-film battery assembly to be laminated is laid between the laminating machine lower cavity and the laminating machine upper cavity; the laminating machine upper cavity is also provided with a electrifying device; the input end of the electrifying device is connected with an outer constant current power supply; the output end of the electrifying device is connected with a bus bar of the thin-film battery assembly to be laminated for performing the electrifying link. On the basis of the laminating technology, the rated electrifying device is added; the electrifying process is simultaneously completed in the laminating process; the process of stabilizing the maximum power of a cadmium telluride thin film solar module is accelerated; the production cost is reduced; the production time is saved; the further reduction of the assembly cost is facilitated; the product competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic solar cells, in particular to a lamination device and a lamination method. Background technique [0002] With the increasing shortage of energy, people pay more and more attention to the development and utilization of solar energy. There is an increasing demand for new solar cells with larger area, higher efficiency and lower production cost. In the field of photovoltaic cells, silicon-based thin films, cadmium telluride (CdTe) thin films, and CIGS thin-film solar cells have attracted widespread attention due to their inherent material properties, development process, and convenience for large-scale continuous production. [0003] The laminator is an important equipment required for the manufacture of solar cell modules. It is a device that presses solar cells, EVA, back sheets and other materials into a whole with certain rigidity and stability under high temperature and vacuum conditions. ...

AI Technical Summary

Problems solved by technology

The current practice is to heat up the battery separately after lamination, keep it warm and apply current, which requires additional equipment and energy, which increases production costs and reduces product competitiveness.
