SM-250 IPCE Measurement System
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).

Features
- Spectral response(A/W) and quantum efficiency(QE) can be measured in the wavelength range of 300 to 1150nm
- Ideal for IPCE/QE evalution of organic solar cells(dye-sensitized,organic thin film,perocskite solar cells)
- The short circuit current density Jsc(mA/cm2) can be calculated based on the spectral response spectrum
- The intarnal quantum efficiency(IQE) can be obtained with optional diffuse reflection measurement unit
