Solar Cell Spectral Measurements System
Testing of spectral response and quantum efficiency of solar cells is an important way to improve the level of technics (such as fuzzing, spreading and back field),judge the quality of silicon materials and research the characteristics of solar cells. 7-SCSpec l/II measurements systems can test spectral response, spectral reflectivity, internal and external quantum efficiency or IPCE（Monochromatic Incident Photon-to-Electron Conversion Efficiency）of solar cells.
