Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and more specifically to a photovoltaic glass and a photovoltaic component. Background Art

[0002] One of the important main materials of photovoltaic modules is photovoltaic glass, which is mainly used for the packaging of photovoltaic modules. Photovoltaic glass will directly affect the power generation efficiency and service life of photovoltaic modules.

[0003] At present, the most commonly used production method for photovoltaic glass is the calendering method. During the formation of photovoltaic glass, the adjusted high-temperature glass liquid is left out from the overflow port, and when passing through the gap between the rollers, it is stretched by the calendering rotation to form the glass body during rolling. The calendering method easily causes tiny ripples to form when the glass is trimmed, resulting in poor appearance and affecting the front appearance of the full-screen component. At present, the existing photovoltaic component glass glazing technology is carried out inside the back glass or inside the front glass, and it is impossible to improve the tiny ripples on the edge of the outer surface when the glass is trimmed. In addition, the connection strength between the existing glaze layer and the photovoltaic glass body is poor, causing the glaze layer to fall off easily. Utility Model Content

[0016] It also includes a plurality of battery cells and bus bars connected to the battery cells, wherein the battery cells and the bus bars are in contact with the inner surface of the photovoltaic glass.

[0017] As a further improvement of the photovoltaic module, the glaze coating area is located at the gap between adjacent battery cells, and the bus bar is located at the glaze coating area.

[0018] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0028] The present invention will be described in detail with reference to the accompanying drawings. What is described here is only a preferred embodiment of the present invention, and those skilled in the art can think of other ways to implement the present invention based on the preferred embodiment, and other ways also fall within the scope of the present invention.

[0029] like Figure 1-3 As shown, this embodiment provides a photovoltaic glass, including a glass body 1 and a glaze layer, and the outer surface of the glass body 1 is divided into a glaze area and a non-glaze area. In this embodiment, after the photovoltaic glass is assembled with the cell and other components into a photovoltaic module, the side of the photovoltaic glass close to the cell is the inner surface of the photovoltaic glass, and the side away from the cell is the outer surface of the photovoltaic glass.

[0030] The outer surface of the glass body 1 is also provided with a concave-convex connection surface, and the concave-convex connection surface is located in the glazed area, and a glazed layer is provided on the glazed area. In this embodiment, the concave-convex connection surface is a serrated surface 13. The glazed layer is printed on the serrated surface 13 by printing, which can enhance the connection strength between the glazed layer and the glass body 1. In addition, the glazed layer is provided on the outer surface of the glass body 1, which can also be used to block the edge ripples caused during the glass processing process, thereby improving the appearance of the photovoltaic module.

[0031] In another case, the concave-convex connection surface is set as a corrugated surface. The glazed area includes an internal glazed area 11 and an edge glazed area 12. During the processing of the glass body 1, tiny ripples are easily formed at the edge. In this case, when the concave-convex connection surface is set as a corrugated surface and the edge of the glass body 1 with tiny ripples is set as the edge glazed area 12, there is no need to process the corrugated surface separately, thereby shortening the processing process of the concave-convex connection surface.

[0032] Furthermore, the internal glaze coating area 11 includes a plurality of transverse glaze coating areas and a plurality of vertical glaze coating areas, the transverse glaze coating areas are arranged at intervals, and the vertical glaze coating areas are arranged at intervals; and the intervals between the transverse glaze coating areas and the vertical glaze coating areas are consistent. Figure 1 The view direction in is described.

[0033] The edge glaze coating area 12 is arranged at the edges of the outer surface of the glass body 1 , and the width of the edge glaze coating area 12 is not less than the width of the inner glaze coating area 11 .

[0034] This embodiment also provides a photovoltaic module, including the photovoltaic glass described above; and also including a plurality of cells and bus bars connected to the cells, wherein the cells and the bus bars are in contact with the inner surface of the photovoltaic glass. The glazed area is located in the gap between adjacent cells to prevent the glazed area from blocking the cells and affecting the power generation efficiency of the photovoltaic module. The bus bar is located in the glazed area, and when viewed from the outer surface of the photovoltaic glass, the bus bar is blocked by the glazed area. The color of the bus bar is inconsistent with the color of other components of the photovoltaic module. By blocking the bus bar with the glazed area, the appearance of the photovoltaic module can be improved.

[0035] The color of the glaze layer can be changed according to the color of the busbars, backplane and other components of the photovoltaic module. It can also be adjusted according to the color of the building where the photovoltaic module is installed to achieve photovoltaic building integration, while meeting the lighting and architectural aesthetics of conventional buildings, while providing clean and environmentally friendly energy.
