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] The present application belongs to the field of photovoltaics, and in particular relates to a photovoltaic cell concentration testing 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-structured 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 outdoor sunlight, but gather a large area of sunlight to a small cell surface through a concentrating lens, so that The unit area of the surface of the solar cel...
