Problems solved by technology

[0002] The front electrode of a conventional solar cell is composed of a metal auxiliary grid line and a main grid line. The shading area of ​​the grid line accounts for 2.5%-3% of the light-receiving area of ​​the solar cell. Since the grid line will block sunlight to a certain extent, the photoelectric conversion efficiency will be reduced. decrease

Abstract

The invention relates to the technical field of solar power generation, in particular to a solar cell, a cutting method of the solar cell and a laminated photovoltaic module. The first surface of thesolar cell is provided with a plurality of first main grids, the second surface of the solar cell is provided with a plurality of second main grids, and no auxiliary grid is arranged between adjacentfirst main grids; projection is carried out in the thickness direction, projections of the plurality of first main grids and projections of the plurality of second main grids are staggered and arranged at equal intervals, and the distance between the adjacent first main grids and second main grids on the projection surface is equal to 1 / 2 of the distance between the adjacent first main grids on the first surface or 1 / 2 of the distance between the adjacent second main grids on the second surface.

Description

technical field [0001] The present application relates to the technical field of solar power generation, and in particular, to a solar cell, a method for cutting a solar cell, and a laminated photovoltaic assembly. Background technique [0002] The front electrode of conventional solar cells is composed of metal auxiliary grid lines and main grid lines. The shading area of ​​the grid lines accounts for 2.5%-3% of the light-receiving area of ​​the solar cell. Since the grid lines will block the sunlight to a certain extent, the photoelectric conversion efficiency decrease. Therefore, it is desirable to research a component that can increase the effective light receiving area, thereby improving the efficiency of the component. SUMMARY OF THE INVENTION [0003] The present application provides a solar cell, a method for cutting solar cells, and a laminated photovoltaic assembly. In the laminated photovoltaic assembly of the present application, there are no gaps between sola...
