Quantitative Information of Electroluminescence Images

2008
The reciprocity between electroluminescence and solar cell quantum efficiency simplifies the simulation and interpretation of electroluminescence spectra. With this reciprocity link, we show how to gain spatially resolved information about recombinatorial and optical parameters from electroluminescence images by using certain types of filters while ...

Photoluminescence and Electroluminescence Imaging of Perovskite Solar Cells

Progress in Photovoltaics: Research and Applications, 2015
AbstractFast camera‐based luminescence‐imaging measurements on perovskite solar cells are presented. The fundamental correlation between the luminescence intensity and the open circuit voltage predicted by the generalised Planck law is confirmed, enabling various quantitative methods for the detection of efficiency‐limiting defects to be applied to ...

Electroluminescence Imaging of PV devices: Determining the image quality

2015 IEEE 42nd Photovoltaic Specialist Conference (PVSC), 2015
A no-reference method determining the image quality of electroluminescence (EL) images is presented. This allows mapping the estimated intensity based uncertainty originating from the EL image itself. Determining the uncertainty will allow for quantitative comparison and analysis of EL images and will define the minimum criteria of an imaging setup at ...

Absolute Characterization of Solar Cells by Electroluminescence Imaging

2021 IEEE 48th Photovoltaic Specialists Conference (PVSC), 2021
In this work [1], we derived a new method to map several optoelectronic parameters of solar cells from voltage dependent electroluminescence imaging. We introduce a calibration factor generally left unknown in the literature. Example is shown on Al-BSF silicon solar cell for which we map the following parameters: diffusion lengths, dopant concentration,

Electroluminescence imaging of organic photovoltaic modules

Applied Physics Letters, 2010
We report on electroluminescence (EL) imaging of organic photovoltaic cells and modules with poly(3-hexylthiophene)/[6,6]-phenyl C61 butyric acid methyl ester as semiconductor layer. The dominant EL emission is found in a spectral regime between 1200 and 1400 nm and is identified as the radiative decay of the charge transfer complex formed between the ...

Comparative Study of the Electrical Parameters of Individual Solar Cells in a c-Si Module Extracted Using Indoor and Outdoor Electroluminescence Imaging

IEEE Journal of Photovoltaics, 2020
In this article, electroluminescence (EL) imaging is applied to characterize monocrystalline silicon photovoltaic (PV) modules under indoor and outdoor conditions. EL images of PV modules are analyzed to extract dark saturation current density and series
