Spectral Sensitivity Measurement
Bunkoukeiki Co., Ltd (Bunkoukeiki)
It is a device which measures the spectral sensitivity characteristics and quantum efficiency of various solar cells by irradiating solar cells with monochromatic light of constant energy and constant photon without wavelength dependence. We are constantly monitoring irradiation light quantity with our real real time light quantity monitor control system and are not influenced by fluctuation of light source, so it is a well-established control system with excellent measurement stability and measurement reproducibility.
