Thiocyanate Free Ruthenium(II) Complexes for Dye Sensitized Solar Cells (DSSCs)

Abstract:

The four thiocyanate free ruthenium(II) complexes; [Ru(N^N)₂(C^N)]PF₆ were synthesized and characterized for dye sensitized solar cells (DSSCs). The results showed that the broad absorptions covered the visible region from metal to ligand charge transfer (MLCT) were obtained with the main peaks at 560, 490 and 400 nm. The materials were studied DSSC performance under standard AM 1.5. Compound PP1 showed the power conversion efficiency (PCE) at 3.10%, with a short-circuit photocurrent density (J_sc) of 7.99 mA cm^-2, an open-circuit photovoltage (V_oc) of 563 mV and a high fill factor (ff) of 0.690.
