Development of an organic redox couple and organic dyes for aqueous dye-sensitized solar cells
A water-sol. org. redox couple (TT-/DTT) and new org. dyes (D45 and D51) have been developed for aq. dye-sensitized solar cells (DSCs). An optimal efficiency of 3.5% was obtained using the D51 dye and an optimized electrolyte compn. The highest IPCE value obtained was 68% at 460 nm.
