Embodiment 1

[0014] see Figure 1-2 , the present invention provides a back light barrier for power testing of double-sided double-glass components, comprising a light barrier 2, the surface of the light barrier 2 is provided with a light refraction part, the outer surface of the light refraction part is provided with a layer of inkjet coating 3, sprayed The ink coating 3 is sprayed with matte black, and the light refraction part is a polygonal cone, and the edges of each group of light refraction parts are connected to each other. The vertebral body is a quadrangular vertebral body and is pyramid-shaped.

specific Embodiment 2

[0016] The difference from the specific embodiment 1 is that the light refraction part is a polygonal cone concave toward the inside of the light blocking plate 2, and the polygonal cone is a quadrangular cone, in the shape of a concave pyramid

[0017] To sum up, when testing the electrical properties of double-sided solar cells or components, the light-absorbing plate with the above-mentioned surface structure will be placed behind the double-sided solar cells or components. In the above-mentioned technical scheme structure, the fundamental principle is Change the angle of light reflection to make multiple reflections. Since the surface of the structure is treated with matte black, after the light is reflected multiple times, the final amount of reflected light will be reduced, improving the light-absorbing effect of the light baffle.

Abstract

The invention discloses a back light barrier applied to power test of a double-sided double-glass assembly, which comprises a light barrier, a light refraction part is arranged on the surface of the light barrier, an ink jet coating is arranged on the outer surface of the light refraction part, the light refraction part is in a polygonal cone shape, and the edges of each group of light refraction parts are connected with one another. The invention relates to a light barrier capable of improving light absorbance by changing the surface, in particular to a back light barrier applied to power test of a double-sided double-glass assembly, and belongs to the technical field of measurement of electrical properties (current, voltage, power, conversion efficiency, irradiation intensity and the like) of solar photovoltaic cells and assemblies. According to the light barrier, multiple times of reflection are conducted by changing the angle of illumination reflection, due to the fact that the surface of the structure is subjected to ink jet coating treatment, after light is reflected for multiple times, the final reflection light amount is reduced, and the light absorption effect of the light barrier is improved.

Description

technical field [0001] The invention relates to a light-shielding plate that changes the surface to increase the light absorption rate, in particular to a light-shielding plate applied to the power test of a double-sided double-glass component, which belongs to solar photovoltaic cells and components with electrical properties (current, voltage, power, conversion efficiency, Radiation intensity, etc.) measurement technology field. Background technique [0002] In the field of photovoltaic module testing, one of the international standards for the measurement of the electrical properties of double-sided solar cells or modules is that the back and the front are completely shaded (that is, the reflectance of the shade is <3%), respectively in the STC Two sets of electrical performance parameters were measured under the same conditions, followed by corresponding procedures, under the condition that the back side is completely shielded, the overall equivalent electrical perfor...
