A review of modeling of luminescent coupling effect in multi-junction solar cell based on diode equation

Abstract

The luminescent coupling effect in multi-junction solar cell is a phenomenon where extra photocurrent in one sub-cell is driven by radiative recombination of electron-hole pairs in another sub-cell. This paper focuses on the analysis of the modeling of luminescent coupling effect in multi-junction solar cell. These modelings are based on the two-diode equivalent circuit. Finally, it concludes that the study of the luminescent coupling effect requires not only a suitable modeling but also a good experimental method for detecting the characteristics of sub-cells in multi-junction solar cell.
