Problems solved by technology

[0002] With the development of photovoltaic cell module technology, multi-grid technology has become the current mainstream technology, and the size of cell modules is getting larger and larger. As the cell version becomes larger, the warpage control of the backplane of the module, such as the edge of double-glass glass Also more difficult, therefore prone to splintering issues when laminating

Embodiment Construction

[0033] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0034] In the embodiment, the photovoltaic module is composed of a solar cell array, a front sheet, a back sheet, etc. During the production and preparation of the photovoltaic module, it will be reworked due to some abnormality or defect in the module, for example, the busbar of the outermost layer of the cell When the line is too close to the edge, the edge warpage of the backplane such as double-glass glass is unavoidable. During lamination, the edge of the double-glass glass is warped and the edge of the cell is relatively stressed. Therefore, the problem of lamination splitting is prone to occur.

[0035] In order to solve the above-mentioned problems, the solar battery sheet of the embodiment of the present invention improves the main grid line 10 an...

Abstract

The invention discloses a solar cell and a photovoltaic module, the cell comprises a plurality of main grid lines and auxiliary grid lines, the plurality of main grid lines are arranged in parallel on the front surface of the cell and extend along the first direction of the cell; a plurality of auxiliary grid lines are arranged in parallel and are vertically intersected with the main grid lines; wherein the first distance between the main grid line arranged close to the first edge of the battery piece and the first edge is larger than or equal to 10 mm, and the first edge is the edge, extending in the first direction, of the battery piece. The solar cell provided by the embodiment of the invention can reduce the risk of layer fracture.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cells, in particular to a solar battery sheet and a photovoltaic module. Background technique [0002] With the development of photovoltaic cell module technology, multi-grid technology has become the current mainstream technology, and the size of cell modules is getting larger and larger. As the cell version becomes larger, the warpage control of the backplane of the module, such as the edge of double-glass glass It is also more difficult and therefore prone to splintering problems when laminating. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to propose a solar cell sheet which reduces the risk of lamination cracks. [0004] The second object of the present invention is to provide a photovoltaic module. [0005] In order to achieve the above obje...
