The spectral responsivity or quantum efficiency (QE) is essential for understanding current generation, recombination, and diffusion mechanisms in photovoltaic devices. PV cell and module calibrations often require a spectral correction factor that uses the QE. The quantum efficiency in units of electron - hole pairs collected per incident photon is computed from the measured spectral response in units of amperes per watt as a function of wavelength. Model HO-SC-QE is integrated with 50W Tungsten Halogen lamp with housing, optics, power supply and an easy to use software with capability to measure the spectral response and quantum efficiency of solar cell at the wavelengths from 400nm to 1200nm.
