Spectral Response Measurement System

1．Spectral Response (CEPseries）


The system 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.


Our unique real-time light intensity monitor control system constantly monitors irradiation light intensity to keep the light intensity constant, and so it is not affected by the fluctuation of the light source. This is a well-established control system with excellent measurement stability and measurement reproducibility.


The CEP series systems and other systems have been delivered to many customers, including the National Institute of Advanced Industrial Science and Technology (AIST) and Japan Electrical Safety & Environment Technology Laboratories (JET).Our systems have become one of the standard measuring instruments for solar

cell performance evaluation in Japan.
