Quantum efficiency (QE)

What is Quantum efficiency (QE)?

Ratio of the quantity of charge carriers captured by a solar cell to the quantity of photons of solar energy reaching the cell. It is related to a photovoltaic cell’s response to different wavelengths in the spectrum of sunlight incident on the cell. Quantum efficiency is expressed as a function of energy or wavelength. In the optimal case, a PV cell should produce considerable electric current for wavelengths prevailing in solar radiation.
