This solar simulator system is used to simulate the sunlight, which is used widely in the photovoltaic devices and QC. The solar simulator can produce the collimation beam, and the light spot is uniform. Spectral Match is class A of the solar simulator system radiation spectrum. This solar simulator system is suit for the monocrystalline silicon, polysilicon, amorphous thin film, dye-sensitized, organic, III-V semiconductors solar cells measurement and so on.
