Embodiment Construction

[0040] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0041] Participate figure 1 As shown, the photovoltaic cell test device includes a support 10, which includes a bottom plate 11 and a top plate 12 that are arranged horizontally. The top plate 12 is located directly above the bottom plate 11, and four guide rods 13 are supported between the bottom plate 11 and the top plate 12 to define the XYZ axis In the coordinate system, the guide rod 13 extends along the Z-axis direction (vertical direction). The bottom plate 1...

Abstract

The invention discloses a photovoltaic cell concentration test device, which comprises a support, a concentration system, a moving platform, a working table, a cell slice fixing device, and a secondary dodging system, wherein the support is provided with a guide rod extending along a Z axis direction; the concentration system is arranged on the support and comprises a diaphragm with an adjustable aperture and a lens located below the diaphragm; the moving platform slides on the guide rod along the Z axis direction; the working table comprises a first working table and a second working table, the first working table slides on the moving platform along a Y axis direction, the second working table is located on the first working table and can move along an X axis direction in relative to the first working table, and the second working table is provided with a bearing surface for bearing a tested cell slice; and the secondary dodging system is located between the lens and the working table. The diaphragm is arranged between the light source and the concentration lens, uniform and parallel light with a large area can be outputted, and through continuously adjusting the area of the aperture of the diaphragm, total light energy received by the to-be-tested cell slice can be adjusted continuously.

Description

Technical field [0001] This application belongs to the field of photovoltaics, and particularly relates to a photovoltaic cell concentration test device. Background technique [0002] In recent years, as a new type of renewable energy, solar cells have attracted more and more attention, and their status in the energy industry has become more and more important. With the continuous development of solar technology and people's continuous in-depth exploration of high-efficiency solar cells, the concentrating solar cell system composed of multiple PN structures of high-efficiency solar cells and concentrating components is bound to become the mainstream of solar cell applications . [0003] For solar cells with multiple PN junctions, in the actual application process, they often do not work directly under the outdoor sunlight, but converge a large area of ​​sunlight onto a small cell surface through a condenser lens. This allows the solar cell surface unit area to receive a light int...
