Solar Cell Quantum Efficiency Test System

Standard Test Equipment for Solar Cell Quantum Efficiency Measurement

The ratio of incident photons to collected electrons in output current is calculated as external quantum efficiency of solar cell based on standard spectral response measurement. Optional instruments allows reflectance measurement and internal quantum efficiency measurement, and automatic positioning.
