Embodiment

[0026] In the method for synthesizing full-band matching solar simulator spectra in this embodiment, Gaussian spectra are used instead of LED spectra, and six kinds of Gaussian spectra are generated with six light sources. The waveband 400nm~1100nm is divided into the first waveband 400nm~500nm, the second waveband 500nm~600nm, the third waveband 600nm~700nm, the fourth waveband 700nm~800nm, the fifth waveband 800nm~900nm and the sixth waveband 900nm~1100nm In the middle of these six bands, that is, the above six Gaussian spectra have center wavelengths of 450nm, 550nm, 650nm, 750nm, 850nm and 1000nm, and the above six Gaussian spectra are focused by mirrors to achieve spectrum synthesis to obtain a full-band matching sun The simulator spectrum 207, the full-band matching solar simulator spectrum 207 in the six bands of the AM1.5G standard, the percentage of the spectral irradiance in the six bands of the total spectral irradiance is fully matched with the AM1.5G standard, The...

Abstract

The invention discloses a method for synthesizing a full-wave-band matching solar simulator spectrum and relates to a light source device special for spectroscopy. Gaussian spectrums are used for replacing spectrums of an LED light-emitting unit, six light sources are used for generating six Gaussian spectrums, and the full-wave-band matching solar simulator spectrum is obtained through synthesizing under reflecting of a reflector. The percentage of the spectral irradiance of the full-wave-band matching solar simulator spectrum in each wave band in the AM1.5G standard is completely matched with that of the full wave bands of the AM1.5G standard, in other words, the percentage of the spectral irradiance of the synthesized spectrum in the total spectral irradiance of the whole six wave bands is completely the same with the the percentage of the spectral irradiance of each wave band in the total spectral irradiance of the whole six wave bands in the AM1.5G standard. According to the method, the defect that the spectral mismatching degree between a synthesized spectrum adopted in the prior art and the spectrum in the AM1.5G standard is deviated is overcome.

Description

technical field [0001] The technical solution of the present invention relates to a light source device specially used for spectroscopy, in particular to a method for synthesizing full-band matching solar simulator spectrum. Background technique [0002] Solar simulators use controllable light sources prepared by existing people, such as mercury lamps, xenon lamps, halogen lamps, and light-emitting diodes (LEDs), etc., through the conversion and synthesis of light waves, to achieve the effect of sunlight. The emergence of the solar simulator provides a simulated solar light source for experiments under the conditions of all-weather and arbitrary locations requiring sunlight, and has been applied in the performance inspection of photovoltaic solar cell power generation, plant growth, semiconductor chip aging, and medical care. In realizing the solar simulator, matching with the solar spectrum is the key. For this reason, the AM1.5G standard, the AM1.5D standard and the AM0 st...
