Abstract
In a solar cell evaluation device 1, a spectral sensitivity P(λ) of a solar cell 2, which is a measurement object, is measured in advance. When the solar cell 2 is evaluated, a spectral irradiance L (λ) of illumination light is measured, generated power EL of the solar cell 2 that is generated with the illumination light is measured, and the measured generated power EL of the solar cell 2 is converted into generated power ES generated by the solar cell 2 in the case of illumination with illumination light with a spectral irradiance S(λ) based on the reference solar light. Therefore, since the calibration in the solar cell evaluation device 1 is performed with software, the calibration can be performed in a simple manner and at a low cost even when the solar cell type is changed.
