The CEP-M1000 has been designed to irradiate solar cells with
monochromatic light of constant energy and constant photons without
wavelength dependence, and measures the spectral response and quantum
efficiency of various solar cells. The CEP-M1000 was developed under the
technical guidance of the National Institute of Advanced Industrial Science
and Technology for the purpose of evaluating the spectral response of
solar cell modules. It targets crystalline and thin-film single-junction solar
cells and multi-junction solar cells. It is possible to measure the spectral
sensitivity of a solar cell module with a maximum size of 1.7 x 1.2 x 0.1M.

Measurement data
The above is External quantum efficiency (EQE) measurement data of multi-junction solar cells measured with the model CEP-M1000.
Features
Spectral response measurement by constant energy irradiation
- The light intensity is adjusted with a continuos density variable ND filter,and constant energy light without wavelength characteristics is irradiated. The spectral response of the sample can be calculated from the irradiation light intensity and the measured photocurrent. The same measurement can be performed performed under white light or color bias light. Bias voltage can be set.
Measurement of quantum effciency by constant photon irrdiation
- The light intensity is adjusted with a continuous density variable ND filter,and constant photon light is irradiated. The quantum effciency of the sample can be calculated from the irradiation light intensity and the measured photocurrent. The same measurement can be performed under white light or color bias light. The bias voltage can be set.
Solar cell characteristics and I-V chraccteristics measurement
- The cell characteristics can be measured with white bias light.
Solar spectrum calculation(IEC 60904-3)
- The short-circuit current density can be calculated from the integration of the solar spectrum and quantum effciency.
