摘要：

Electrolyte modification is shown to have a substantial effect on the understanding and optimization of n-CdSe/ferricyanide photoelectrochemical solar cells. A series of pentacyanoferrate(II) complexes, [Fe(CN)5L]3- aqueous are prepared (L = CN-, NH3, (CH3)2SO, H2O, NO+, NO2- and Fe(CN)53-), and their substantial variation in photoelectrochemical activities at n-CdSe are correlated to their spectral and electrochemical properties. Investigation into ferro/ferricyanide speciation showed that in the alkaline pH region where ferrocyanides are most photoelectroactive, monocation ferrocyanide and ferricyanide species dominate, MFe(CN)63-/2-. These cation derivatives (M = Mg2+, Ca2+, Li+, Na+, K+, Cs+, NH4+) are varied, and the potassium derivative was shown to result in both high photopotentials and facile kinetics.
