A stacking process of crystalline silicon photovoltaic modules

Abstract

The invention discloses a lamination operation process of a crystalline silicon photovoltaic module, comprising the following steps: laying glass on a lamination template, making the lamination template flush with the edge of the glass, taking a piece of non-stained isolation EVA, and making it Cover on the glass, and exceed the edge of the glass by 3mm‑5mm; then place the cell on the glass, and overlap with the laminated template, and mark the circuit of the laminated template; take a clean isolation backplane , align the outer edge with the edge of the glass, and paste high-temperature fixing tape along the marked line, and use a 6C specification soldering iron tip to fix the cell between the glass and the backplane; For lamination, use high-temperature fixing tape to paste and connect with soldering iron tip to ensure product quality and production efficiency, and effectively solve the phenomenon of product scrapping. At the same time, EPE pads and EVA pads are used to simplify the operation of product stacking , which increases the controllability of the operation and reduces the cycle of product processing.

Description

technical field [0001] The invention belongs to the field of photovoltaic manufacturing, and in particular relates to a processing technology of a photovoltaic module, more specifically a lamination operation technology of a crystalline silicon photovoltaic module. Background technique [0002] Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. [0003] The photovoltaic module stacking process uses tempered glass as the carrier, and the series-connected battery strings are correctly connected with the bus belt on the vinyl acetate copolymer (EVA film) according to the requirements of the design drawings, and spliced ​​into the required battery square array. And cover the vinyl acetate copolymer (EVA film) and the back sheet material to complete the lamination process. In order to ensure the correctness of splicing electrodes during the stacking process, the ...

Problems solved by technology

[0005] At present, during the production of photovoltaic modules in the stacking process, product scrapping occurs frequently due to complex operation steps, which greatly wastes production materials, and at the same time, the products produced have poor performance and do not meet the competitive needs of the market. The announcement number CN102332490A is published A photovoltaic module laminated laying process. Due to the complicated steps in the production of this process, a lot of manpower and material resources are required. At the same time, strict specifications are required in the selection of raw materials, which is not suitable for production lines. Human operation is difficult accomplish
