Abstract:
1. A measurement method of measuring a current-voltage characteristic of an object to be measured including a plurality of photovoltaic cells using a solar simulator including a light source having a lamp and a reflector, comprising: disposing an irradiated test plane of the object to be measured opposite an illuminating surface of said light source; dividing a whole of the test plane of the object to be measured into a plurality of imaginary sections corresponding to respective photovoltaic cells; disposing members for adjusting irradiance opposite respective imaginary sections of the test plane so as to equalize or to substantially equalize irradiance of the object to be measured by the light source at respective sections of the test plane corresponding to the imaginary sections; and directing light from said light source onto the test plane of the object to be measured, wherein the object to be measured produces the current-voltage characteristic to be measured in response to said light.
