Evaluation of Novel Photoresponsive Materials via EQE Measurements
Internal Quantum Efficiency (IQE) and External Quantum Efficiency (EQE) measurements are indicators of the effectiveness of a photosensitive device such as those used in telecommunications and solar cells. EQE is the ratio of the charges generated to the total amount of photons incident on the surface; a larger EQE indicates a more efficient device.
