Problems solved by technology

When the above-mentioned solar cell module is working, the light directly shines on the gap between the battery sheet and the back plate through the glass, and the light directly on the battery sheet is absorbed by the battery sheet, and then converted into electrical energy; and the light directly on the gap, because the surface of the back plate is generally uniform As a planar structure, light is reflected directly out (see Figure 2~3 shown), cannot be used by the cells, resulting in the loss of part of the power

Embodiment 1

[0050] Both the reflective strips in Embodiment 1 and Implementation 2 have an insulating structure (separation groove 9 and insulating layer 10 ), so as to avoid short circuit caused by electrical connection between adjacent cells when the reflective strip is installed in the gap.

[0051] The processing steps in the preparation method in the implementation one and the embodiment two are partly similar, and it all comprises the following steps:

[0052] Step 1: use glass fiber or PET material to melt into a flat plate shape, heat and remelt again to form the bottom plate 7;

[0053] Step 2: Use precision gears to press the upper surface of the bottom plate 7 to form a reflective structure that reflects sunlight; the reflective structure is a pyramid suede structure, and the specific processing parameters are 1~3mm 2 Press into 5~15 pyramid structures with a base angle of 20~50 degrees within the range;

[0054] Step 3: Using Physical Vapor Deposition (Physical Vapor Depositi...

Abstract

The invention discloses a reflective stripe for a solar cell component. The reflective stripe is elongated, a reflection structure is arranged on the reflective stripe which is provided with a soleplate made from an insulated or semi-conductor material, the reflection structure for reflecting sunlight and a metallic diaphragm layer; the reflection structure is a protrusion formed on the upper surface of the soleplate, the metallic diaphragm layer is formed on the upper surface of a reflection mechanism; and the reflective stripe is also provided with an insulation structure which can separate adjacent cell sheets at both sides of the reflective stripe in an insulation mode. The reflective stripe in the invention can favorably reflect sunlight to the cell sheets, improves the efficiency of the solar cell component, has favorable insulation performance, avoids short-circuit conditions possibly occurring between the cell sheets and ensures the safety performance of the cell component.

Description

technical field [0001] The present invention relates to a solar component, a component of a solar cell component using the component and a preparation method of the component, in particular to a reflective strip for reflecting sunlight on a battery sheet, a corresponding solar component and the preparation of the corresponding reflective strip method. Background technique [0002] At present, the continuous use of conventional energy has brought about a series of economic and social problems such as energy shortage and environmental degradation, and the development of solar cell modules is one of the ways to solve the above problems. Therefore, all countries in the world are actively developing solar cell components, and high conversion efficiency and low cost are the main trends in the development of solar cell components, and are also the goals pursued by technical researchers. [0003] See the attached solar cell module for the packaged solar cell module Figure 1~3 As s...
