Embodiment Construction

[0010] Example: Encapsulate the battery pack according to the following steps: The photovoltaic cell encapsulation process includes the following steps: 1. Front welding: use a welding machine to weld the busbar to the main grid line of the negative electrode on the front of the cell. The busbar is a tinned copper strip. The length of the ribbon is twice the length of the side of the battery, and the excess ribbon is connected to the back electrode of the battery behind when welding on the back;

[0011] 2. Backside series connection: Backside welding is to connect the battery pieces in series to form a component string. The battery pieces are positioned on the mold plate. There are grooves for placing the battery pieces on the mold plate. Correspondingly, weld the positive and negative electrodes of the "front cell" to the back positive electrode of the "rear cell", and the cells are connected in series to form a module string, and the leads are welded to the positive and nega...

Abstract

The invention discloses a photovoltaic cell packaging technology for a double-sided glass curtain, which comprises the following steps: front side welding, back side serial connection, laminated laying, component lamination and battery trimming. The photovoltaic cell packaging technology can vacuumize and remove air bubbles by lamination with good lamination effect; the lamination is performed by several times to ensure that the relative position of a component string and glass and the like, and the lamination quality is high; and the curing time is short and the production efficiency is high.

Description

technical field [0001] The invention relates to a battery packaging process, in particular to a double-sided glass curtain wall photovoltaic cell group packaging process. Background technique [0002] At present, the country vigorously advocates the development of green energy, and photovoltaic cells are one of them. The utilization rate and qualification rate of photovoltaic cells are closely related to the packaging process of battery packs. On the one hand, the existing packaging process is easy to form air bubbles, which reduces the efficiency of the battery. On the other hand, the lamination is performed at one time, which takes a long time for lamination and low production efficiency. Contents of the invention [0003] The object of the present invention is to provide a double-sided glass curtain wall photovoltaic battery group packaging process, the packaging of the photovoltaic battery is simple and reliable, the lamination time is short, and the production efficie...
