Problems solved by technology

[0004] At present, solar power generation tiles with functions of power generation and building materials have come out on the market, which form crystalline silicon cells on the surface of the tile substrate, use crystalline silicon cells to absorb solar energy, and convert it into usable electrical energy; however, solar energy When the power generation tile is used as a building material, the edge part of the tile base of each solar power generation tile is generally a curved surface or a special-shaped structure, so as to realize the overlap or hardware connection between the two solar power generation tiles, so that the crystalline silicon cells can only form In the flat area of ​​the tile base, the actual occupied area of ​​the crystalline silicon cell in the tile base is small, and the surface of the tile base cannot be fully utilized, resulting in a relatively low utilization rate of the tile base of the photovoltaic power generation tile.

Embodiment 1

[0037] see Figure 1 ~ Figure 3 The photovoltaic power generation tile provided by the embodiment of the present invention includes a tile base 1, a first cell 2 and a second cell 3; the tile base 1 can be a metal tile, a clay tile, a cement tile, a ceramic tile or Glass tiles etc. are not listed one by one here.

[0038] The tile base 1 includes a flat plate portion 10 and at least one raised portion connected to the flat plate portion 10; the flat plate portion 10 and at least one raised portion can be of an integrated structure or a split structure, but considering the convenience of manufacture, the flat plate portion 10 and at least one raised portion in one piece.

[0039] The outer surface of the flat part 10 is formed with a first battery sheet 2, and the outer surface of at least one raised part is formed with a second battery sheet 3 matching the outer surface of the raised part; the raised part can be a bridge member of the tile base 1 , it can also be a raised pa...

Embodiment 2

[0064] The embodiment of the present invention also provides a photovoltaic power generation tile. The difference between the photovoltaic power generation tile and the photovoltaic power generation tile provided in the first embodiment above is that:

[0065] Such as Figure 7 ~ Figure 9As shown, the above-mentioned first battery slice 2 includes a plurality of sub-first battery slices 20 connected in series. Wherein, the first battery piece 2 is arranged on the flat plate portion 10 , and the light-receiving area and light intensity of each part thereof are the same, so the arrangement of the plurality of sub-first battery pieces 20 is relatively free.

[0066] Of course, the specific structure of the first cell 2 included in the photovoltaic power generation tile provided in Embodiment 1 can also be referred to Figure 8 and Figure 9 way to set.

[0067] Such as Figure 8 ~ Figure 9 As shown, the second battery slice 3 includes multiple groups of sub-second battery sli...

Embodiment 3

[0092] Such as Figure 10 As shown, the embodiment of the present invention also provides a photovoltaic power generation system, which includes a plurality of photovoltaic power generation tiles described in the first or second embodiment above.

[0093] Compared with the prior art, the beneficial effect of the photovoltaic power generation system provided by the embodiment of the present invention is the same as that of the photovoltaic power generation tile provided by the above technical solution, and will not be repeated here.

[0094] Specifically, in the embodiment of the present invention, the first battery slice 2 and the second battery slice 3 included in each photovoltaic power generation tile are connected in parallel, and each photovoltaic power generation tile is connected in series to ensure the maximum current output.

[0095] Such as Figure 1 to Figure 5 , Figure 7 and Figure 10 As shown, when the number of ridges included in each photovoltaic power gene...
