Problems solved by technology

The existing technology has the following problems: sometimes the soldering does not work, and sometimes it is over-soldered. In addition, it is easy to cause false soldering, tin beads, delamination of the busbar of the cell, and high solder joints. At the same time, the fluidity of the solder is poor, and the soldering reliability is poor; After welding, the appearance is poor in flatness and brightness, and the layer is easy to peel off and the silver layer is easy to fall off; the damage rate of the product after welding is high; the inspection of the finished product after welding also shows that the output power of the component is not ideal
In short, the performance of solar cell modules is not ideal

Abstract

This invention relates to a method for manufacturing solar energy battery components including: 1, welding several solar energy battery plates to a unit with a prepared mutual connection strip, 2, laminating glass EVA / solar energy battery array / EVA / TPT from the bottom to top in a vacuum laminating machine, 3, pumping the lower chamber of the laminating machine with a vacuum laminating method to press the glass / EVA / solar energy battery series / EVA / TPT together and take them out after molding, 4, mounting frames to get the components characterizing in applying an electric iron of constant temperature in small temperature error sphere to solder prepared strips together to increase the welding quality.

Description

(1) Technical field: [0001] The invention relates to a method for manufacturing a solar battery module. Involved in the field of solar photovoltaic technology. (two) background technology: [0002] The single solar cell is made of silicon single crystal or polycrystalline material. Because it is thin and brittle, it cannot withstand a large impact, the electrodes of the solar cell cannot be used exposed for a long time, and the working voltage of the single solar cell is low. A number of single solar cells are connected in series, parallel and tightly packed into a solar cell module to make it a minimum unit that can be used independently as a power source. [0003] The requirements for solar cell components can be summarized as follows: a certain nominal operating voltage and a certain nominal output power; long working life; sufficient mechanical strength; small loss of electrical properties caused by combination; small combination cost . [0004] The manufacturing meth...
