Large Stokes shift downshifting Eu(III)films as efficiency enhancing UV block…

Large Stokes shift downshifting organolanthanide complex,Eu(tta)3phen, is examined for inclusion in polymeric layers to replace the UVblocking layer in dye sensitized solar cell (DSSC) technology. The UV blocking layer increases stability but power conversion efficiency decreases as incident UV photons are not converted into photocurrent. Eu(tta)3phen doped polymeric film are prepared and atta…
