Problems solved by technology

[0002] In the existing photovoltaic modules, the shading of the front of the cell welding is too large, which affects the power generation of the cells to a certain extent
The electrical connection between the battery sheets is realized through the interconnection ribbon. Due to the excessive current of a single cell or a half-cut battery, the current flowing through the interconnection ribbon is also large, resulting in high resistance loss of the ribbon and serious output power loss.
In addition, the current component prices are getting lower and lower, and the pressure of component cost reduction is increasing. Therefore, a large space for cost reduction is required

Embodiment Construction

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] combine Figure 1 to Figure 3 As shown, Example 1 discloses a novel cell structure. like figure 1 As shown, the front side of the battery sheet includes four strip-shaped modules 1 arranged in parallel. The strip-shaped modules 1 are of rectangular design as a whole, and a gap D1 is provided between adjacent strip-shaped modules. On the one hand, the width of the gap D1 should meet the cutting process, and should not be too n...

Abstract

The present invention discloses a solar battery piece, which includes the N -type module of the parallel layout. The gap D1 is left between the adjacent strip modules.Two edges that are arranged in parallel in the main grid and parallel in the vertical direction constitute the N rectangular frames; the strip module also includes the M collection unit in the rectangular frame.The fine grid lines and two welded joints used on the two -time main grid are arranged on the two main grids; the two ends of the fine grid line are directly or indirectly connected to the solder joints;electrode.Further use the photovoltaic component made from the above battery.The present invention can achieve point interconnection during the production of components, greatly improving the power generation efficiency of components, and reducing the cost of component production.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a novel solar cell sheet and a photovoltaic assembly. Background technique [0002] In the existing photovoltaic modules, the shading on the front side of the cell welding is too large, which affects the power generation of the cell to a certain extent. The electrical connection between the cells is realized by interconnecting ribbons. Due to the excessive current of a single cell or a half-cut cell, the current flowing through the interconnecting ribbons is also large, resulting in high resistance loss of ribbons and serious output power loss. . In addition, the current component prices are getting lower and lower, and the pressure on component cost reduction is increasing. Therefore, a large space for cost reduction is required. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention discloses a new type of solar cell an...
