Patent ID: 8918298

Claim:
A solar cell evaluation device comprising: an illumination unit that illuminates a solar cell that is a measurement object; a spectral irradiance measurement unit that measures a spectral irradiance L (λ) by monitoring a spectrum and an irradiance of illumination light radiated from the illumination unit; a power measurement unit that measures a generated power EL of the solar cell illuminated with the illumination light; and a calculation unit that performs a calibration with software when the measured spectral irradiance L (λ) is different from a spectral irradiance S(λ) of a predetermined reference solar light, even when spectral sensitivity of the solar cell is changed, by converting the generated power EL of the solar cell measured by the power measurement unit into a generated power ES generated by the solar cell in the case of illumination of the reference solar light with the spectral irradiance S(λ), such conversion is calculated using the measured spectral irradiance L(λ),a spectral sensitivity P(λ) of the solar cell that has been measured in advance and the spectral irradiance S(λ).
