Determination of the Collection Diffusion Length by Electroluminescence Imaging
Energy Procedia, 2011 The electroluminescence emission of crystalline silicon solar cells at near-bandgap wavelengths is investigated. We show that the intensity of the emitted luminescence at near-bandgap wavelengths is directly proportional to the collection diffusion length Lc which is a measure of bulk and rear surface recombination properties and determines the short ...

Electroluminescence from HgTe Nanocrystals and Its Use for Active Imaging [PDF]
Nano Letters, 2020 Mercury telluride (HgTe) nanocrystals are among the most versatile infrared (IR) materials with the absorption of lowest energy optical absorption which can be tuned from the visible to the terahertz range. Therefore, they have been extensively considered as near IR emitters and as absorbers for low-cost IR detectors.

Electroluminescence Imaging of PV Devices: Advanced Vignetting Calibration
IEEE Journal of Photovoltaics, 2018 Electroluminescence (EL) imaging is affected by off-axis illumination together with sensor and lens imperfections. The images’ spatial intensity distribution is mainly determined by the vignetting effect. For quantitative EL imaging, its correction is essential. If neglected, intensities can vary significantly (>50%) across the image.
