Defining Critical Parameters in a Luminescent Downshifting Layer for PV Enhancement

This chapter presents the study and evaluation of luminescent down shifting (LDS) layers doped with organic dyes their compatibility different types solar cells. In this study, commercial in Lumogen-F series (BASF) Violet 570, Orange 240, Red 300, Yellow 083, 170 were considered for analysis. It was found that while fulfil important characteristics materials LDS such as high photoluminescent quantum yield, small radiative overlap, absorption or close to UV range emission visible spectrum. Nevertheless, due low Stokes shift, do not entirely align spectral response cells matching are depend on external efficiency cell. chapter, a design matrix developed outlined cell types. For parameters cells, optimised layer can be chosen.
