Embodiment 1

[0024] like Figure 4 As shown, the test surface of this scheme is a triple-junction laminated solar panel, and the spectrum adjustment mechanism includes three kinds of filter adjustment sheets. Further, each of the above three filter adjustment sheets in this solution includes two filter adjustment sheets with the same light transmission wavelength threshold. The two filter adjustment sheets are arranged on the radial position of the light column, and the spectral components of the light source are adjusted by adjusting the area of ​​the light path blocked by them.

Embodiment 2

[0026] like Figure 5 As shown, the test surface of this scheme is a four-junction laminated solar panel, and the spectrum adjustment mechanism includes four kinds of filter adjustment sheets. Wherein, each filter adjustment sheet includes one filter adjustment sheet, and the four filter adjustment sheets are arranged in horizontal and vertical radial positions, and the spectral components of the light source are adjusted by adjusting the area blocked by the light path.

[0027] This scheme also discloses another solar simulator that can split light, that is, the filter of the light source processing device is a light splitting filter, and the light splitting filter divides the light source into a long-wave light source and a short-wave light source, and the light reflected by the light-splitting filter After being reflected by the reflector, the short-wave light source is introduced into the homogenizer through the variable aperture and filter adjustment sheet, and the long-w...

Abstract

The invention relates to a solar light source simulator. The simulator comprises a simulation light source, a light source processing device and a light projection device, and the simulation light source comprises a short-arc xenon lamp. The short-arc xenon lamp is arranged in an elliptical curved surface reflection cup; the light source processing device comprises a light filter and a light homogenizer; the light projection device comprises a plurality of reflectors and a projection lens, light emitted by the xenon short-arc lamp is condensed to a focus through the elliptical curved surface reflection cup, a light filter is arranged on a light path in front of the focus, the light homogenizer is arranged on the focus, and the filtered and homogenized light is projected to the reflectors and reflected to the projection lens to become parallel light to be superposed on a test surface. According to the invention, an improved light source processing scheme is adopted to provide a uniformand stable simulated solar spectrum, and the solar light source simulator has the characteristics of good simulation effect and high performance.

Description

technical field [0001] The invention relates to a solar light source simulator, in particular to an improved solar light source simulator, which belongs to the field of solar light source simulators. Background technique [0002] The solar simulator is a device that uses artificial light sources to simulate sunlight for production, testing and other processes. The simulated sunlight should have the characteristics of uniformity, stability, and spectral similarity. The basic principle is to use artificial light sources to simulate solar radiation. In order to overcome the shortcomings of solar radiation being affected by time and climate, and the total irradiance cannot be adjusted, it is widely used in the field of photovoltaic cell testing. A solar simulator with good performance can guarantee the realization of the production process and improve the quality of the product. Contents of the invention [0003] The solar light source simulator of the invention discloses a n...
