A practical triple spectrum solar simulator is designed and developed in this paper. The spectral match of this solar simulator can adjust intensity of three spectral bands(300-700 nm, 700-900 nm, 900-1 700 nm), which can meet the test requirement of triple junction GaInP/GaAs/Ge solar cell after spectrum correction. This paper first describes the design of the filter and the process of system spectrum correction and testing, and then introduces the optical system and mechanical structure of the solar simulator. The experiments show that the solar simulator′s spectral match meet triple junction GaInP/GaAs/Ge solar cell′s response currents. In the effective irradiated surface area of 150 mm×150 mm, the average irradiance reaches 2 730 W/m2, the irradiance non-uniformity reaches ±177%, and the irradiance temporal instability is up to ±083%. The solar simulator provides a stable and reliable platform for the solar cell automatic sorting system.
