Each light filtering adjusting sheet comprises a light filtering adjusting sheet, the four light filtering adjusting sheets are arranged at horizontal and vertical radial positions, and the spectral components of the light source are adjusted by adjusting the area of a light path shielded by the four light filtering adjusting sheets.
The scheme also discloses another light-splitting solar simulator, namely, a light filter of a light source processing device is a light-splitting light filter, the light source is split into a long-wave light source and a short-wave light source by the light-splitting light filter, the short-wave light source reflected by the light-splitting light filter is guided into a light homogenizer through an iris diaphragm and a light filtering adjusting sheet after being reflected by a reflector, the long-wave light source transmitted by the light-splitting light filter is guided into the light homogenizer through the iris diaphragm and the light filtering adjusting sheet, and the light filtering adjusting sheet adjusts the wavelength threshold of transmitted light. Based on the above scheme, the scheme discloses a solar simulator for detecting a four-section laminated cell panel, as shown in fig. 7, a simulation light source comprises a simulation light source unit a and a simulation light source unit B, and a light source processing device comprises a filtering unit a, a filtering unit B and a light homogenizer. The light filtering unit A comprises a light splitting filter A, a light source of the simulation light source unit A is split into a long-wave light source A and a short-wave light source A by the light splitting filter A, the short-wave light source A is guided into the light equalizer through the iris diaphragm and the short-wave light filtering adjusting sheet A after being reflected by the reflector, the long-wave light source A is guided into the light equalizer through the iris diaphragm and the long-wave light filtering adjusting sheet A, and the light transmitting wavelength threshold values of the short-wave light filtering adjusting sheet A and the long-wave light filtering adjusting sheet A are different.

Further, in order to realize the function of the light homogenizer, the light homogenizer of the scheme comprises a plurality of quartz light pipes, one end of each quartz light pipe receives the light source passing through the light filtering adjusting sheet, the other end of each quartz light pipe is connected into the light homogenizer body, the light homogenizer body comprises a fly eye lens, the fly eye lens comprises a plurality of sub lenses, and the plurality of sub lenses divide incident light into a plurality of sub light sources. The light uniformizer can divide the light emitted from each light guide end face into a plurality of sub-light sources, each sub-light source can independently emit light and can be overlapped together at a distance, and therefore uniform light spots are formed.
The scheme discloses a solar simulator, which mainly simulates sunlight, and uniformity, stability and spectrum are the most important indexes. The scheme adopts a short-arc xenon lamp as a light source and carries out coupling through an elliptical reflecting cup. The light emitting point of the short-arc xenon lamp is positioned on one focal point of the elliptical reflecting cup, and the light emitted by the xenon lamp is collected and focused to the other focal point. A filter is placed in front of the focus to adjust the spectrum of the xenon lamp so that it is generally close to the spectrum of the sun. The light uniformizing device is arranged at the focus position and can divide and recombine light, so that a single light source is changed into a plurality of sub-light sources to be projected out, and then the light is changed into parallel light through the projection lens to be superposed on the test surface. Finally, the light on the test surface meets the requirements of uniformity, stability and spectrum. The constant light source simulator can meet the test requirements of most single junction battery plates. But for the multi-junction laminated cell test, the special requirements are put on the spectrum of a simulator, and the traditional solar simulator cannot meet the requirements. Taking an InGaP/GaAs/Ge three-junction cell as an example, the top cell is made of InGaP and can convert light of 300-700 nm in sunlight into electricity, the middle cell is made of GaAs and can convert light of 500-900 nm in sunlight into electricity, and the bottom cell is made of Ge and can convert light of 900-1800 nm into electricity. The test of the three-junction cell requires that the solar simulator can be close to the solar spectrum in a large range of 300-1800 nm, and the spectrum of the solar simulator can be independently adjusted (increased and decreased) in three ranges of 300-700 nm, 500-900 nm and 900-1800 nm. The traditional solar simulator adopts a single-chip optical filter to integrally regulate the spectrum of a xenon lamp, so that the spectrum is close to the solar spectrum in a wide range of 300-1800 nm, but the spectral components are fixed and cannot be independently regulated in three intervals of 300-700 nm, 500-900 nm and 900-1800 nm.
In order to solve the above problems, in the present solution, a spectrum adjusting mechanism is disposed on a light path in front of the optical filter, as shown in fig. 2, a light spot emitted by the spectrum adjusting mechanism is annular, as shown in fig. 3, three sets of optical filters (filter adjusting sheets) are added in the annular light spot, as shown in fig. 4, the optical filters can move independently and freely extend into or extend out of the light spot. The transmittance curve of the optical filter corresponds to each junction battery interval, so when the optical filter extends into the light spot, the spectral components of the junction are reduced, the spectral components of the rest junctions are basically unchanged, and when the optical filter extends out of the light spot, the spectral components of the junction are increased, and the rest components are basically unchanged. Thus, the spectrum of each junction can be independently adjusted. The scheme can be expanded and applied to solar cells with 4 junctions, 5 junctions and 6 junctions. For example, for a 4 junction cell, the filters for each corresponding junction are shown in fig. 5. In addition, in the simulator, the filter can be driven by a stepping motor to move back and forth, as shown in fig. 6.
The scheme also discloses another solar simulator capable of splitting light. Sunlight hits the multi-junction cell, and the wavelength from short to long can be absorbed by the first junction, the second junction, the third junction and the fourth junction in sequence and converted into electric energy. To test a multi-junction cell, a solar simulator is required to be capable of independently adjusting the light intensity of each junction of the multi-junction cell, and independent of each other, so that the solar simulator cannot influence each other. As shown in fig. 7, the inner side of the reflector is an ellipse, and the wick of the short-arc xenon lamp is placed at one focus of the ellipse, and the light emitted by the short-arc xenon lamp is automatically converged at the other focus. The quartz light pipe is placed at the far focus of the ellipse and collects the light of the xenon lamp. The spectral filter can divide the light of the xenon lamp into a long wavelength and a short wavelength, wherein the long wavelength is transmitted, and the short wavelength is reflected. The iris diaphragm can adjust the size of light entering the quartz light guide by adjusting the size of the diameter of the central hole. Only the light corresponding to each junction of the multi-junction cell is transmitted out into the quartz light guide through the optical filter (filter adjusting sheet). Fig. 7 uses 2 lamps and 2 reflectors, 2 dichroic filters, 4 junction filters (filter tuning sheets) to split the light into 4 independent bands corresponding to the response interval of the multijunction cell, and into 4 quartz light guides. Wherein, the intensity of the light intensity can be adjusted by each wave band through the respective variable aperture. The light homogenizer employs a fly's eye system, which is composed of many very small sub-lenses. The light uniformizer can divide the light emitted from each light guide end face into a plurality of sub light sources, each sub light source can independently emit light and can be superposed together at a distance, and therefore uniform light spots can be formed. The projection lens can collimate each sub-light source formed on the light equalizer, and finally, the light hitting the test surface becomes uniform and collimated, and is similar to sunlight.
The solar light source simulator of the present invention is not limited to the disclosure of the specific embodiments, the technical solutions presented in the examples can be extended based on the understanding of those skilled in the art, and the simple alternatives made by those skilled in the art according to the present invention in combination with common general knowledge also belong to the scope of the present invention.
