In this work, a fluorinated resin is presented as host material for luminescent downshifting (LDS) applications carried out on polymer solar cells. The results obtained by depositing coatings with increasing concentrations of an appropriate organic fluorescent molecule on polymer solar cells show a trend with a maximum short circuit current density increase (+3.74%) at intermediate concentrations (1% wt.). Such behavior has been successfully correlated with the photo-physical properties of the coatings. These results highlight the suitability of LDS as a straightforward strategy for improving the performance of polymer solar cells without modifying the chemistry of the photoactive layer.

Abstract
In this work, a fluorinated resin is presented as host material for luminescent downshifting (LDS) applications carried out on polymer solar cells. The results obtained by depositing coatings with increasing concentrations of an appropriate organic fluorescent molecule on polymer solar cells show a trend with a maximum short circuit current density increase (+3.74%) at intermediate concentrations (1% wt.). Such behavior has been successfully correlated with the photo-physical properties of the coatings. These results highlight the suitability of LDS as a straightforward strategy for improving the performance of polymer solar cells without modifying the chemistry of the photoactive layer.File | Dimensione | Formato | |
