The intensity of irradiation(mW/cm2) at each wavelength is measured with a calibrated silicon photodiode, and the current value of the mesurement sample is measured based on irradiation intensity.The dedicated software(SR_PRO) can automatically display the spectral response and quantum efficiency of various solar cells and photoelectric conversion elements. Our unique xenon lamp optical system and high-effciency monochromator make it possible to irradiate hige intensity monochromatic(5mW/cm2), making it ideal for evaluating oraganic solar cells(dye-sensitized,orgainc thin films,perovskite solar cells).
