Problems solved by technology

[0002] With the rapid improvement of cell conversion efficiency, the conversion efficiency of solar modules has become an important factor restricting the cost of solar power generation systems. At present, the conversion efficiency of mass-produced solar cells has exceeded 25%, while the conversion efficiency of traditional mass-produced solar modules is less than 20%. , there is still room for improvement in the conversion efficiency of solar modules
[0005] However, the disadvantage is that the density of planar packaging of components tends to be saturated, and it is difficult to continue to increase; moreover, the planar packaging technology of components determines that the irradiance of the light-receiving surface of the components is closely related to the angle of incident light. It is also changing; when the component is subjected to external force or deformation, the component planar packaging technology will inevitably bear the mechanical load of the cell itself, the reliability of the component is limited, and the scope of use is limited

Embodiment 1

[0022] Example one, as attached to the instructions figure 2 As shown, the incident light Line a is perpendicular to the glass layer 1 on the light-receiving surface. The incident light will be reflected and reused in this design structure. The cell 5 and the upper glass layer 1 of the light-receiving surface form a certain angle, so that the incident light The back battery sheet 5 and the triangular support 4 can be reused after reflection, and the packaging density of the components is improved. In addition, the triangular support 4 can carry all the mechanical loads, and the battery itself is not affected by any external force.

Embodiment 2

[0023] Embodiment two, as attached image 3 As shown, the incident light Line b and Line c are directed to the glass layer 1 on the light-receiving surface obliquely from both sides. Under light of different incident angles (except for vertical incident light), the components all have the main light-receiving surface cell 5 and The secondary light-receiving surface cell 5, and the two are complementary, the total output voltage and current of the module will not have large fluctuations.

[0024] As a preference, the angle between the hypotenuse of the triangular bracket 4 and the upper glass layer 1 or the lower glass layer 2 is set to be 5°-45°, which allows a wide choice of installation angles for the components, a wide range of trials, and easy adjustment of the solar cell 5 and the light receiving. The installation tilt angle of the glass layer 1 on the surface.

[0025] As a preference, the width of the cell 5 is set to 20-50 mm. In the present invention, the cell 5 is a small...

Description

Technical field [0001] The invention relates to the technical field, in particular to a solar module packaging structure. Background technique [0002] With the rapid increase in cell conversion efficiency, the conversion efficiency of solar modules has become an important factor restricting the cost of solar power generation systems. At present, the conversion efficiency of mass production of solar cells has exceeded 25%, while the conversion efficiency of traditional mass production solar modules is less than 20%. , The conversion efficiency of solar modules still has room for improvement. In recent years, solar modules have improved the conversion efficiency of solar modules in terms of material light transmittance, light secondary reflection utilization, and high-density module packaging. However, with the increase in the packaging density of solar modules (such as shingling, patchwork, etc.), the effective packaging area utilization rate of the modules is close to saturatio...
