Abstract
A solar simulator and a measurement method of the multi-junction photovoltaic device is provided. The measurement method includes following processes. The process that the halogen lamp emits a flash and a top of a light pulse wave shape is controlled to be flat. The process that the xenon lamp once or plural times emits a flash which has the flat top and is shorter pulse than the flat area of the halogen lamp flash while the top of a light pulse shape of the halogen lamp flash is flat. The process that the flashes from the halogen lamp and the xenon lamp is irradiated to the photovoltaic device as the measurement object, and during the emission of the flash from the xenon lamp, the load of the photovoltaic device is controlled and the current and the voltage generating therefrom are measured at single point or plural points.
