Laminator for preparing photovoltaic modules and the preparation process of photovoltaic modules, photovoltaic modules

Abstract

The laminator for preparing photovoltaic modules, the manufacturing process of photovoltaic modules and the photovoltaic module provided by the present disclosure relate to the field of photovoltaic modules. The preparation process steps of the photovoltaic module in the present disclosure are simple, require less improvement on the existing laminator, and have high process stability. The preparation process of the photovoltaic module in the present disclosure includes the following steps: (1), pretreatment before lamination; (2), lamination treatment; (3), cooling; 4), post-processing. Its beneficial effects are: the present disclosure simply transforms the laminator—the positive and negative conductive metal foils are set on the high-temperature cloth of the conventional laminator, and at the same time, the material feeding table and the vacuum chamber of the conventional laminator , and the metal beam at the junction of the vacuum chamber and the lamination chamber, the pneumatic tooling probe is installed on the metal beam, and the pneumatic tooling probe is connected to the current source to form a component electrification circuit, which realizes the perfect combination of component lamination process and electric injection hydrogenation combined.

Description

technical field [0001] The present disclosure relates to the field of photovoltaic modules, in particular to a laminator for preparing photovoltaic modules, a preparation process for photovoltaic modules, and photovoltaic modules. Background technique [0002] At present, boron-doped P-type silicon wafers are widely used in crystalline silicon solar photovoltaic modules. When the solar module made of boron-doped P-type silicon wafer is exposed to sunlight, the performance of the battery will decay, and finally reach a stable value of battery performance. This phenomenon is usually called light-induced attenuation. [0003] According to relevant research reports, the efficiency decay rate of single crystal boron-doped all-aluminum back field conventional single crystal silicon cells is 2-3%, and the efficiency decay rate of single crystal boron-doped single crystal PERC cells is 3-5%. The attenuation mechanism is generally believed to be due to the existence of boron-oxygen ...

Problems solved by technology

[0006] The above method needs to increase the illumination radiation chamber and cooling chamber on the basis of the existing laminator of the conventional production line, which includes 3 chambers: vacuum chamber, lamination chamber, and cooling chamber. In addition, the patent requires particularly high contact accuracy between the probe and the component electrode, and in this patent, the probe and the component electrode are in contact with the cavity, which is not easy to observe and adjust. Therefore, the technical solution disclosed in the patent It is very difficult to implement and not easy to promote
