Abstract

The invention discloses a photovoltaic module and a preparation process thereof, and relates to the technical field of photovoltaic cells, the photovoltaic module comprises a cell string, a back welding strip arranged on one side of the back of the cell string, a front welding strip arranged on the other side of the front of the cell string, a second bus bar, a first bus bar and an insulating isolation strip, the first bus bar is located on one side of the back of the cell string, and the second bus bar is located on the other side of the front of the cell string; connecting with a back welding strip; the part, exceeding the other side of the front surface of the battery string, of the front-surface welding strip is arranged on the surface of the insulating isolation strip; the second bus bar is located on the front solder strip on the surface of the insulating isolation strip. In order to solve the technical problem of material waste caused by large size of the photovoltaic module, the size of the photovoltaic module can be reduced by changing the structure and the preparation process of the photovoltaic module, and the module material is saved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cells, in particular to a photovoltaic component and a preparation process thereof. Background technique [0002] Conventional photovoltaic modules are composed of photovoltaic cell units connected in series through interconnecting ribbons to form battery strings, and then the battery strings are then upgraded in series and parallel to larger battery cell arrays through busbars, for example, according to 6*10, 6* 12, 6*13, 5*11 arrays, or other cell array structures such as 6*10*2, 6*12*2, 6*13*2, 5*11*2, etc., to form components with a certain power. The interconnecting ribbon is generally welded on the bus electrodes on the front and back sides of two adjacent cells. Generally, the current carried is relatively small, so the cross-sectional area is also very small, generally not exceeding 0.1mm. 2 . The busbars of conventional photovoltaic modules will additionally occupy more dimensions ...
