Experimental validation of adding-doubling modeling of solar cells including luminescent down-shifting layers

Luminescent down-shifting (LDS) layers applied on top of solar cells can potentially increase solar cell performance due to the better match of the incident irradiance spectrum reaching the cell to its spectral response. In this study, the adding-doubling tool is presented, which allows fast predictions of the influence of LDS sheets on solar cell performance. The model is validated by comparing its predictions to experimental data. Four LDS sheets including different conversion materials were investigated. The modeling tool was able to predict the external quantum efficiency with an average deviation of 0.02.status: publishe
