Poster summary

A new model for the photocurrent density calculation in solar cells with Luminescent Down-Shifting Layers is developed. The effects due to the Luminescent Down-Shifting layer on the spectral reflectance and transmittance are included for the cell ́s multiple layer optical performance. It is shown that a Lu3Al5O12:Ce3+ layer on top of a CdTe solar cell might cause an efficiency increase around 21%.
