Embodiment 1

[0022] according to figure 1 As shown, multiple sunlight solar panels are superimposed on the front, including solar panels, and two solar reflective panels connected to the solar panels. The lower edge of the solar reflector is connected to the side of the solar panel, and the solar reflector is connected to the solar panel The angle a between the panels is 100°.

Embodiment 2

[0024] according to figure 2 and image 3 As shown, "multiple sunlight solar panel components stacked on the front", including a solar panel, and a solar reflection plate connected to the solar panel, will add a layer of reflected sunlight on the front of the solar panel. The solar reflector is rectangular, and the lower edge coincides with the side of the solar panel (when the solar panel is a square, the solar reflector can also be a square), and the angle a between the solar reflector and the solar panel is 120° . (The area of ​​the solar reflector is preferably equal to or larger than the area of ​​the solar panel. If it is smaller than the area of ​​the solar panel, the efficiency will not achieve the best effect. The area of ​​the reflected sunlight needs to coincide with the area of ​​the solar panel. Sunlight reflection In the case of a certain panel area, adjusting the angle between the solar reflector and the solar panel will increase or decrease the area of ​​ref...

Embodiment 3

[0039] according to Figure 4 and Figure 5 As shown, "multiple sunlight solar cell modules stacked on the front", including solar cell panels, and four solar reflectors with the same area and size connected to the solar cell panels, so that four layers of stacked panels will be obtained on the front of the solar cell module. Solar reflected light. The reflector is rectangular (the solar cell panel can be square or in any shape, and the sunlight reflector can also be in a corresponding square or in any shape), and the connection mode is that the bottom edge of each reflector coincides with the side of the solar cell Arranged symmetrically in a cross shape, the angle a between the solar reflector and the solar panel is 120° (the area of ​​the solar reflector is preferably equal to or greater than the area of ​​the solar panel, if it is smaller than the area of ​​the solar panel, the efficiency of the reflection system cannot be sufficient Play. The area of ​​the reflected su...

Abstract

The invention belongs to the technical field of photovoltaic power generation equipment, and particularly relates to a solar cell module with superposed multiple sunlight at the front and a method for superposing multiple sunlight at the front of the solar cell module. According to the technical scheme, the solar cell module with the superposed multiple sunlight at the front comprises a solar cell panel and at least one sunlight reflecting plate connected with the solar cell panel, and an included angle alpha between each sunlight reflecting plate and the solar cell panel is more than 90 degrees and less than 180 degrees. The absorbance of a solar cell is improved to the maximum extent, the photoelectric conversion rate (more than or equal to 30%) of the solar cell panel is greatly increased, and cost is reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation equipment, and in particular relates to a method for superimposing multiple sunlight solar cell components on the front and superimposing multiple sunlight on the front. Background technique [0002] The theoretical upper limit of the photoelectric conversion rate of monocrystalline silicon solar cells is 27%, and the current maximum value is about 24%. Factory production can only reach 14%-16%, and the highest conversion rate of solar cells is 18%. Then the factors that affect the conversion rate of solar cells mainly include the following aspects: reflection loss: more than 30% of the light is reflected by the silicon surface; electrode shading loss: about 4% - 15%; transmission loss: mainly medium and long The wave light of 800μm-1300μm is penetrated from the back of the battery, about 15%-30%. On this basis, how to improve the conversion rate of solar cells has become a ...
