[0002] The photovoltaic tiles in the prior art generate a large amount of heat while generating electricity. Since the photovoltaic tiles have a poor heat dissipation effect, the power generation efficiency of the photovoltaic tiles will be reduced. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, the first object of the utility model is to provide a power generating tile.

[0005] The second objective of the utility model is to provide a photovoltaic module.

Specifically, the photovoltaic elements are mounted on the mounting plate, and any photovoltaic element includes a solar cell, which can receive light and convert light energy into electrical energy, so that the power-generating tile has the function of generating electricity.

[0008] Furthermore, the side of the photovoltaic element facing the mounting plate is a curved surface, and any photovoltaic element and the mounting plate enclose a heat dissipation cavity, and the curved surface of the photovoltaic element facing the mounting plate constitutes a part of the cavity wall of the heat dissipation cavity. Understandably, the solar cell generates heat in the process of converting light energy into electrical energy, which in turn causes the temperature of the photovoltaic element to rise. If the temperature of the photovoltaic element is too high, the power generation efficiency of the photovoltaic element will decrease. In order to improve the power generation efficiency of the photovoltaic element, the present application forms a heat dissipation cavity for heat dissipation between the photovoltaic element and the mounting plate. The heat generated by the photovoltaic element during the power generation process can be dissipated into the heat dissipation cavity. Since the heat dissipation cavity is connected to the outside world, the hot air in the heat dissipation cavity can flow out to the outside world, and at the same time, the cold air from the outside world flows into the heat dissipation cavity to cool the photovoltaic element.

[0009] By setting the side of the photovoltaic element facing the mounting plate as a curved surface, the photovoltaic element and the mounting plate can be combined to form a heat dissipation cavity.

[0076] In this embodiment, the installation method of the mounting plate 110 in the photovoltaic assembly 200 is defined. The photovoltaic assembly 200 may have a plurality of mounting plates 110. When there are a plurality of mounting plates 110, the plurality of mounting plates 110 are overlapped in sequence along the length direction of the mounting plates 110 and / or the width direction of the mounting plates 110. Since the overlap between two adjacent mounting plates 110 has an overlapping area, it has a certain waterproof effect, so that the photovoltaic assembly 200 has a certain waterproof sealing property.

[0077] In a possible embodiment, Figure 1 and Figure 2 As shown, one side of the power generating tile 100 is a plurality of curved parts (i.e., photovoltaic elements 120), and the other side is a flat substrate (i.e., mounting plate 110), and a plurality of hollow tubular structures (i.e., heat dissipation chambers 122) are formed between the curved parts and the flat substrate. The curved parts are vacuum structures formed by double-layer glass (i.e., first light-transmitting parts 123 and second light-transmitting parts 124), the first layer of glass (i.e., first light-transmitting parts 123) is transparent glass, and the back of the second layer of glass (i.e., second light-transmitting parts 124) is encapsulated with solar cells 121, and the heat generated by the power generating tile 100 during photovoltaic power generation fills the tube cavity (i.e., heat dissipation chamber 122). The flat substrate is a vacuum plate, and the curved parts are single solar panels with power generation function. The curved parts are bonded to the flat substrate by structural adhesive or by accessories, or the flat substrate is provided with mounting grooves adapted to the curved parts.

[0078] like Figure 3 As shown, one end of the bending piece is large and the other end is small. When multiple bending pieces are installed, the large end of the bending piece is sleeved on the small end of another bending piece.

[0079] like Figure 4 As shown, the tube cavities of the interconnected bending parts are connected, and the tube cavities at both ends are connected to the external channel, connected to the heat pump 215, to collect hot air and input cold air.

[0080] The flat substrate is made of a material with good thermal insulation performance, such as a sheet coated with a heat-reflective coating or thermal insulation cotton, a polyurethane foam board, etc.

[0081] The power generating tile 100 proposed in this application has the following technical effects:

[0082] 1. The hollow tubular structure is formed by the shape of the product itself, and the surrounding structures are all vacuum structures, which can well keep warm and have good heat collection function. It can effectively provide energy for the heat pump 215 and realize the utilization of waste heat;

[0083] 2. The flat floor is made of vacuum insulation material, which has good indoor space insulation effect and creates ultra-low energy consumption buildings;

[0084] 3. After the waste heat is discharged through the heat collection channel (i.e., the air inlet pipe 213), the temperature of the power generation tile 100 is reduced, and the power generation can be increased;

[0085] 4. The vacuum structure makes the surface and bottom temperatures of the power generating tile 100 both at normal temperatures. In sunny summer, there is no need to worry about high surface temperatures and normal maintenance can be carried out. At the same time, the roof surface temperature is at normal temperature, allowing birds to contact the roof, which is eco-friendly and will not cause damage to the environmental food chain.

The terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium.
