Design and characterization of effective solar cells

2.1 Quantum efficiency of solar cells. The quantum efficiency ((Q_e)) of a solar cell is the ratio of charge carrier produced at the external circuit of the cell (electronic device) to the number of photons received (or absorbed) by the cell.There are two ways this quantum efficiency ratio is calculated: (i) external quantum efficiency and (ii) internal quantum efficiency.
