Embodiment 1

[0027] Embodiment 1: as figure 2 The photovoltaic module shown includes several slices of solar cells. The slices of solar cells are formed by cutting the solar cells. , this effect will be reduced due to the position parallel to the laser sliced ​​lobes during welding.

[0028] Since the present invention performs laser slicing in a direction parallel to the main grid, if the image 3 The production process of the conventional half-cell module shown is a series of steps of laser scribing, splitting, welding, lamination, lamination, frame installation, junction box installation, and testing. The welding volume of the battery sheet is double that of the original production line , additional welding equipment needs to be added and modified.

[0029] In order to adapt to laser slicing parallel to the direction of the main grid, the present invention changes the sequence of welding, laser scribing, and slivers. Figure 4 The component preparation process shown is carried out, ...

Abstract

The invention discloses a photovoltaic module which comprises a plurality of solar battery piece slices, wherein the solar battery piece slices are formed by cutting a solar battery piece along a direction parallel to a main grid line. Meanwhile, the invention further discloses a manufacturing process of the photovoltaic module. The manufacturing process comprises the following steps: welding the solar battery piece, performing laser scribing along the direction parallel to the main grid line of the solar battery piece to form a cutting channel, and slicing the solar battery piece according to the cutting channel; and performing stacking, lamination, framing, wiring box arrangement and test. The photovoltaic module overcomes the technical bottleneck and the bias in the conventional solar field; the solar slicing direction is creatively designed to be parallel to the main grid line, so that on-line production of a slice assembly can be realized, and fragments are reduced; and compared with the yield of a conventional half battery module, the yield of the photovoltaic module is greatly increased.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a photovoltaic component and a preparation process thereof. Background technique [0002] High-power, low-cost crystalline silicon solar modules are the mainstream development direction of the photovoltaic industry. In recent years, with the development and progress of technology, the power of crystalline silicon solar modules has been increasing rapidly. From the beginning of 2009 to the present, the industry's 60 polycrystalline The mainstream power has increased from 220W to 265W, and the mainstream power of 60-cell monocrystalline modules has increased from 230W to 275W. According to the growth trend of module power, the mainstream power of polycrystalline modules will reach 270-280W in 2016 and 2017 to meet the power requirements of modules. At the same time, the National Development and Reform Commission and other eight departments issued the "Energy Efficie...
