Concentration effects on the performance of bis(diimine) copper(I) dyes in dye-sensitized solar cells

For the stepwise assembly of a copper(I) bis(diimine) dye, [Cu(Lanchor)(Lancillary)]+, the concentration of [Cu(Lancillary)2]+ used for on-surface ligand exchange has a profound influence upon the rate at which an optimum JSC is attained and on the final value of JSC; this necessarily influences the global efficiency of the DSCs.
