Detailed Description

In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Example 1

As shown in fig. 2, the present embodiment provides a small-curvature convex surface component device, the device includes a cover plate 1, a battery piece 2 and a bottom plate 3, the battery piece 2 is disposed between the cover plate 1 and the bottom plate 3, the cover plate 1 is located on the top of the battery piece 2, the bottom plate 3 is located on the bottom of the battery piece 2, the top surface of the cover plate 1 is provided with at least one protrusion, and the cover plate 1 and the protrusion are made of a material that can transmit sunlight.

Specifically, in the present embodiment, the battery piece 2 is disposed between the cover plate 1 and the bottom plate 3, and the cover plate 1 is made of a material with high solar transmittance, such as glass. The solar rays are incident on the cell 2 through the cover plate 1, so that the sunlight is absorbed by the cell 2. At least one protrusion is provided on the top surface of the cover plate 1, as shown in fig. 3. The convex structure may form the top surface of the cap plate 1 into a surface having a curvature. When the solar ray is emitted to the cover plate 1 in an inclined direction having a certain angle, the protrusion can refract the solar ray, thereby generating a refracted ray perpendicular to the cell 2. According to the irradiation characteristics of the cell 2, the power generation efficiency of vertical irradiation is improved by multiple levels compared with that of non-vertical irradiation. Although the convex part may increase the incident angle of part of the solar rays, the small-curvature convex component device proposed in this embodiment still has much higher power generation efficiency than the conventional flat glass shown in fig. 1 through practical application and calculation.

In addition, in the embodiment, the protrusion and the cover plate 1 may be integrally formed, so as to reduce the energy loss of the sunlight between the protrusion and the cover plate 1. The number of the bulges and the arrangement on the surface of the cover plate 1 can also be determined according to the position and the specific situation of the sun on site. If the number of the protrusions is large, the protrusions can be uniformly distributed on the top surface of the cover plate 1, so as to increase the probability that the solar rays are vertically incident on the battery piece 2 as much as possible.

Further, a material with high temperature resistance and high light transmittance can be filled between the cover plate 1 and the bottom plate 3 for fixing the battery piece 2. This embodiment can be implemented by using POE material 4. Of course, other materials with the above properties may be substituted, and the embodiment is not particularly limited.

Be provided with a frame 5 respectively in the left and right sides of apron 1 and bottom plate 3, this frame 5 can be fixed apron 1, bottom plate 3 and battery piece 2 as a whole on the one hand, and on the other hand also can be fixed the convex surface subassembly device of small curvature on treating the external component of installation through this frame 5. The specific structure of the frame 5 may be designed or adjusted according to the structure of the external component to be installed, and this embodiment is not particularly limited.

In addition, it should be noted that, although the solar ray is incident vertically, the power generation efficiency of the ordinary flat glass photovoltaic module may be higher than that of the convex module device with small curvature proposed in this embodiment. However, in real life, the ratio of the case of the vertical incidence of the solar rays to the case of the whole incidence is extremely small due to the movement of the sun. Therefore, the power generation efficiency of the common flat glass component is high only in a very short time. The small-curvature convex surface component device proposed in this embodiment has the condition that the refracted light is vertically irradiated on the cell at each moment. Therefore, the average daily power generation efficiency of the convex surface component device with small curvature proposed in this embodiment is higher than that of the ordinary flat glass component. In addition, the convex device with small curvature of the present embodiment is more advantageous in special installation situations, such as when the light is always incident obliquely. Meanwhile, the convex component device with small curvature provided by the embodiment can also increase the appearance of the whole component device through the design of the bulge, improve the ornamental value of the component device and improve the added value.
