Internal Quantum Efficiency

Internal Quantum Efficiency is a performance metric that quantifies the ratio of charge carriers collected within a optoelectronic device to the number of electron-hole pairs generated by absorbed photons, excluding losses due to reflection and transmission, thereby distinguishing it from external quantum efficiency in photodetectors, light-emitting diodes, and photovoltaic devices.
