Spectral sensitivity measuring apparatus and spectral sensitivity measuring method

摘要

The spectral sensitivity measuring device measures the short-circuit current and spectral sensitivity of the solar cell when it receives any one of a plurality of irradiation lights with different light amounts superimposed on light in a narrow wavelength band. The desired short-circuit current is determined based on the short-circuit current measured by the measurement unit and the spectral sensitivity when the short-circuit current is measured when the plurality of irradiation lights are sequentially irradiated individually. A spectral sensitivity calculation unit that calculates the spectral sensitivity of the predetermined narrow wavelength band when measured. Therefore, such a spectral sensitivity measuring apparatus can obtain the spectral sensitivity at a desired short-circuit current even if the short-circuit current fluctuates because the irradiation light is not stabilized while measuring the spectral sensitivity.
