Abstract:
1. A solar simulator for measuring current-voltage characteristics of photovoltaic devices, characterized in that light without localized unevenness of irradiance irradiates a test plane of a photovoltaic device to be measured, the solar simulator apparatus comprising: a light source comprising a lamp and a reflector; means for mounting the photovoltaic device to be measured in such a way that the test plane of the photovoltaic device is disposed opposite said light source; and means for adjusting irradiance of the light from the light source comprising a plurality of shading members of different opacities for adjusting the irradiance of the light source and a planar support panel for supporting the shading members, a whole test plane of the photovoltaic device being divided into a plurality of sections exceeding in number the plurality of shading members, each shading member disposed opposite a respective one of the plurality of sections of the photovoltaic device, the light from the light source irradiating the test plane of the photovoltaic device through the means for adjusting irradiance.
