电致发光（EL）测量的几个CdTe太阳能电池，GaAs太阳能电池，和AlGaAs LED。的平均集成EL强度，归一化曝光时间和注入电流密度，以及与理想的开路电压和测量的开路电压之间的差异，几乎独立于电池的细节或均匀性。这种趋势适用于不同吸收体材料的器件，但不适用于在亮和暗电流-电压（J-V）曲线之间表现出差的叠加的器件。
Electroluminescence (EL) measurements of several CdTe solar cells, a GaAs solar cell, and an AlGaAs LED were performed. The mean integrated EL intensity, normalized to exposure time and injection-current density, correlates well with the difference between ideal open-circuit voltage and measured open-circuit voltage, nearly independently of cell details or uniformity. This trend holds for devices of different absorber materials but does not hold for devices which exhibit poor superposition between light and dark current-voltage (J-V) curves.
