Embodiment Construction

[0023] As mentioned in the background section, the photoelectric conversion efficiency of solar cells in the prior art needs to be improved.

[0024] The inventors found that the front pattern of photovoltaic cells in the prior art is mainly composed of thin grid lines and busbars, and the cells at the positions of the thin grid lines and busbars cannot receive light, so they cannot generate electricity, which limits The improvement of the photoelectric conversion efficiency of the photovoltaic cell means that the thin grid lines and busbars limit the increase of the light-receiving area of ​​the photovoltaic cell, thereby limiting the improvement of the photoelectric conversion efficiency of the photovoltaic cell.

[0025] In view of this, an embodiment of the present invention provides a photovoltaic cell, comprising

[0026] A battery sheet, the front of the battery sheet has a plurality of thin grid lines;

[0027] A first photovoltaic ribbon that is located on the side o...

Abstract

The embodiment of the invention provides a photovoltaic cell and a photovoltaic component. The photovoltaic cell comprises a battery cell, a first photovoltaic solder strip and a conductive coating, wherein the frontage of the battery cell is provided with a plurality of fine grid lines, the first photovoltaic solder strip is located at certain side departing from the battery cell, of the fine grid line, and is directly welded with the fine grid line, and the first photovoltaic solder strip comprises a copper substrate which is located on an alloy layer on the surface of the copper substrate; the electric coating is directly welded with the fine grid line and the melting point of the conductive coating is lower than the melting point of an alloy. According to the photovoltaic cell provided by the invention, a main grid line can be omitted, the electric connection between the fine grid line and the solder strip can be realized by adopting a way that the fine grid line is directly welded with the first photovoltaic solder strip, the photic area of the photovoltaic cell can be improved, and the photovoltaic conversion efficiency of the photovoltaic cell can be improved; furthermore, the temperature of the melting point of the conductive coating is less than the temperature of the melting point of the alloy, the welding between the fine grid line and the first photovoltaic solder belt can be realized, the fragment ratio in the process of making the photovoltaic cell can be reduced, and the manufacturing cost of the photovoltaic cell can be reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cells, in particular to a photovoltaic cell and a photovoltaic module including the photovoltaic cell. Background technique [0002] With the increasing energy consumption, environmental problems such as excessive carbon dioxide emissions and frequent smog weather are becoming more and more serious, making the demand for green energy imminent in various countries.
