Embodiment 1

[0042] Embodiment 1 Solar cell photovoltaic module

[0043] The solar cell photovoltaic module provided by the present invention includes several cells arranged in a matrix, such as figure 1 As shown, the light-receiving surface of each battery sheet 10 is distributed with four main grids 21 in longitudinal rows and 32 thin grids 22 in the horizontal direction. Of course, the number of main grids 21 and thin grids 22 can be increased or decreased according to needs. EXAMPLE Just to give an example, the main grid 21 collects the current on the fine grid 22 connected thereto. The battery sheet 10 is obtained by dividing the ordinary battery sheet by two horizontal parallel lines, which is 1 / 3 of the ordinary battery sheet. The short side length L2 is 52.25±0.25 mm, which can be selected within the range of 31-54 mm. The width d of the main grid 21 is 0.5-0.6 mm, which can be extended to 0.4-0.7 mm.

[0044] Such as figure 2 As shown, the solar cell photovoltaic module includ...

Embodiment 2

[0050] Embodiment 2 Horizontal solar cell photovoltaic module

[0051] Such as Figure 5 As shown, the horizontal solar cell photovoltaic module includes two solar cell photovoltaic modules 1 arranged side by side, that is, along the long side direction of the battery sheet 10, and a bus bar 4 that collects the current of the interconnection bars. The strip 4 is parallel to the long side of the battery sheet 10, and a virtual conductive line 5 is connected between the two solar cell photovoltaic modules 1 through a diode (not shown in the figure), and the virtual conductive line 5 can be a conventional thin busbar . The virtual conductive wire 5 is isolated from the battery sheet 10 by an insulating material. The insulating and isolating material can be conventional EPE material or transparent insulating EPC or a transparent back plate, so as to ensure that the virtual conductive line 5 does not directly contact the battery sheet 10 . The junction box (not shown in the figu...

Embodiment 3

[0054] Embodiment 3 vertical solar cell photovoltaic module

[0055] Such as Image 6 As shown, the difference from Embodiment 2 is that, in the solar cell photovoltaic modules 1 arranged side by side, the number of columns of the matrix of battery sheets 10 is 3 and the number of rows is 20. Set out the vertical solar cell photovoltaic module. The series interconnection strips 33 are arranged in a density of every three rows, that is, every two rows.

Abstract

The invention relates to the technical field of a solar cell and especially relates to a solar cell photovoltaic module and a solar cell photovoltaic assembly. The solar cell photovoltaic module comprises a plurality of cells in matrix arrangement. The light receiving surface of each cell is provided with a plurality of main grids and fine grids. The main grids collect current of the fine grids connected therewith; and the current collected by the main grids is transmitted through interconnection strips communicated with the main grids. The module is characterized in that the solar cells are rectangular in shape. The solar cell photovoltaic assembly comprises modules and a bus bar. Two adjacent modules are connected through a diode or through a virtual conductor wire and a diode; and the bus bar and the conductor wire are connected and output through a conjunction box. By reducing the size of each cell, the current of each solar cell is reduced, the main grids are narrowed, and internal consumption is reduced in square multiples, thereby improving generation power.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell photovoltaic module and a solar cell photovoltaic assembly. Background technique [0002] With the rise of energy prices, the development and utilization of new energy has become the main topic of research in the field of energy. Because solar energy has the advantages of no pollution, no regional restrictions, and inexhaustible supply, the study of solar power generation has become the main direction for the development and utilization of new energy. Using solar cells to generate electricity is a major way people use solar energy today, but existing solar cells have the following disadvantages: [0003] 1. At present, the arrangement of cells is as follows: the spacing between cells is 2mm, and the spacing between strings is 3mm. The blank area of ​​the entire solar cell module is relatively large, and the utilization rate of power generation is not high. Altho...
