Abstract: Large-scale full solar spectrum irradiation system is an important part of the solar simulator. Irradiation non-uniformity is one of the key technical indexes for the large-scale solar simulator. Some technical problems about difficultly meeting the national standard and the poor optical spectra matching property of light sources exist in traditional solar simulators. Regarding the present issues of the large-scale solar simulators, a full-spectrum irradiation system was designed, and the irradiation uniformity of the system was simulated by using the software Zemax. An innovative concept, irradiance decay pattern, is put forward, and the irradiation uniformity is optimized in this way. A plasma light source produced by So-laronix, Switzerland is used, and the spectrum of full-spectrum solar irradiation system can reach Level A of IEC standard. The irradiance of the proposed system was tested by using a spectral radiometer in the full-spectrum scope. The test results show, when the irradiance is 280 W/m2, the irradiance nonuniformity is 5.7% if the irradiance decay pattern is switched on, or 8.4% if the pattern is off. Referring to the national standard GB/T12637—90 General specification for solar simulator, in the effective radiation area of 2 400 mm×6 000 mm, the irradiance uniformity is better than Level C, and almost reaches Level B.
