In addition, the battery string layer of curved power generation tiles generally has welding strips, which affects the aesthetics of photovoltaic products, and the battery cells are prone to breakage during the lamination process. Utility Model Content

[0003] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the utility model provides a photovoltaic tile.

[0005] In view of this, according to the first aspect of an embodiment of the utility model, a photovoltaic tile is provided, which includes: a first plate body and a second plate body; a battery assembly, which is arranged between the first plate body and the second plate body, and the battery assembly includes a plurality of battery cells, and the plurality of battery cells include at least adjacent first battery cells and second battery cells, and a part of the first battery cell and a part of the second battery cell overlap and are electrically connected; wherein, at least one of the first plate body and the second plate body is constructed as a rigid curved panel, and the rigid curved panel includes a plurality of curved portions connected in sequence.

[0006] The photovoltaic tile provided by the embodiment of the utility model comprises a first plate body, a second plate body and a battery assembly. Specifically, the battery assembly is arranged between the first plate body and the second plate body. Optionally, the first plate body is located on the light-receiving side of the battery assembly, and the second plate body is located on the backlight side of the battery assembly. The first plate body can transmit light, so that under light conditions, the battery assembly can convert light energy into electrical energy.

[0007] The battery assembly includes multiple battery cells, which include at least a first battery cell and a second battery cell. The first battery cell and the second battery cell are adjacent to each other, and a portion of the first battery cell overlaps with a portion of the second battery cell, that is, any two adjacent battery cells in the multiple battery cells partially overlap.

[0008] That is, the multiple cells are stacked cells. Compared with the single cell and the conventional cell spacing cell in the related art, it can ensure the consistency of the appearance of the battery assembly and improve the aesthetics of the photovoltaic tile.

[0009] The overlapping part of the first battery cell and the second battery cell is electrically connected, that is, any two adjacent battery cells among the multiple battery cells are electrically connected by using the shingling technology, that is, the battery assembly adopts a solder strip-free design, which can effectively avoid the solder strip being set on the light-receiving side of the battery assembly and blocking the light-receiving surface of the battery assembly, thereby improving the power generation efficiency of the photovoltaic tiles.

[0010] Moreover, since the battery assembly is not provided with a welding ribbon, there is no stress concentration of the welding ribbon. During the lamination process, the battery cell is not easy to break, and there is a larger process adaptation space.

[0011] In addition, since there is no welding ribbon, the stress pulling of the welding ribbon can be avoided when the battery module is bent and shaped, so that the battery module is easier to bend and the photovoltaic tile has a larger curvature, thereby improving the aesthetics of the photovoltaic tile.

[0012] In addition, since no welding strip is required when the first battery cell and the second battery cell are electrically connected, the manufacturing process is simple, which is conducive to reducing the production cost of photovoltaic tiles.

[0013] At least one of the first plate body and the second plate body is configured as a rigid curved plate. Specifically, the first plate body is a rigid curved plate. Alternatively, the second plate body is a rigid curved plate. Alternatively, both the first plate body and the second plate body are rigid curved plates. The configuration may be based on actual needs.

[0014] The rigid curved panel includes a plurality of curved parts connected in sequence, so that the photovoltaic tile has a high degree of similarity with ordinary roof tiles, thereby improving the aesthetics of the roof.

[0015] In addition, the photovoltaic tile provided according to the above technical solution of the utility model also has the following additional technical features:

[0016] In some technical solutions, optionally, the bending directions of any two adjacent bending portions among the multiple bending portions are opposite.

[0017] In this technical solution, at least one of the first plate and the second plate is defined as a rigid curved plate with multiple peaks and troughs, so that the photovoltaic tiles have a higher degree of similarity with ordinary roof tiles, thereby ensuring the integrity and aesthetics of the roof appearance.

[0018] In some technical solutions, optionally, the battery assembly also includes a conductive connector, which is arranged at the overlapping portion of the first battery cell and the second battery cell and is located between the first battery cell and the second battery cell, and the first battery cell and the second battery cell are electrically connected through the conductive connector.

Specifically, the conductive connector is arranged at the overlapping portion of the first battery cell and the second battery cell, and the conductive connector is located between the first battery cell and the second battery cell. That is to say, any two adjacent battery cells among the multiple battery cells are electrically connected through the conductive connector to achieve series connection.

[0020] Compared with the related art in which any adjacent cells are connected by welding strips, the welding strips can effectively avoid blocking the light-receiving surface of the cell assembly, thereby improving the power generation efficiency of the photovoltaic tile. In addition, during the lamination process, stress concentration at the location of the welding strips can be avoided, which can lead to cell breakage, and facilitates the bending and shaping of the cell assembly.

[0021] In some technical solutions, optionally, each battery cell includes a positive electrode layer and a negative electrode layer; the negative electrode layer of the first battery cell and the positive electrode layer of the second battery cell are electrically connected via a conductive connector.

[0022] In this technical solution, it is defined that each battery cell includes a positive electrode layer and a negative electrode layer.

[0024] In this technical solution, it is defined that each cell also includes a chip layer. Specifically, along the thickness direction of the cell, the positive electrode layer and the negative electrode layer are located on both sides of the chip layer. Thus, when any two adjacent cells overlap, they are electrically connected through conductive connectors, without the need for welding strips, simplifying the preparation process and reducing the production cost of photovoltaic tiles.

[0025] Optionally, the cell comprises a shingled crystalline silicon cell.

[0026] Optionally, the positive electrode layer is located on the light-receiving side of the chip layer, and the negative electrode layer is located on the backlight side of the chip layer.

[0027] In some technical solutions, optionally, the overlapping portion of the first battery cell and the second battery cell is an overlapping region; and the conductive connecting member is located in the overlapping region.

This can achieve effective connection between any two adjacent solar cells while avoiding the conductive connector from blocking the light-receiving surface of the solar cell due to its excessive width, thereby increasing the power generation of the photovoltaic tile.

[0029] In some technical solutions, optionally, along the width direction of the battery cell, the first end of the conductive connector is flush with the end of the first battery cell in the overlapping area; and / or along the width direction of the battery cell, the second end of the conductive connector is flush with the end of the second battery cell in the overlapping area.

[0030] In this technical solution, along the width direction of the cell, the first end of the conductive connector is flush with the end of the first cell in the overlapping area, thereby ensuring that the conductive connector does not extend beyond the outer edge of the overlapping area to improve the power generation efficiency of the photovoltaic tiles while ensuring effective connection between any two adjacent cell sheets, thereby improving the reliability of the photovoltaic tiles and extending the service life of the photovoltaic tiles.

[0032] In some technical solutions, optionally, the conductive connecting member includes a conductive glue.

[0033] In this technical solution, it is defined that the conductive connecting member includes a conductive adhesive, thereby simplifying the preparation process of the photovoltaic tiles and reducing the production cost of the photovoltaic tiles.

[0034] In a specific embodiment, the negative electrode layer of the first shingled battery cell (first battery cell) and the positive electrode layer of the second shingled battery cell (second battery cell) are overlapped with each other through conductive glue. When the battery cell group (battery assembly) is under high temperature and high pressure, the conductive glue will melt and overlap the positive and negative electrodes of the two shingled battery cells together. When the temperature returns to room temperature, the positive and negative electrodes of the two shingled battery cells are fixed together, thereby realizing the series connection of the battery cells.
