N2 - The CdS(Se)-electrolyte interface provides a relatively efficient means of converting optical energy into electricity. A [Cd(Fe(CN)6]2-/1- overlayer is demonstrated to stabilize these semiconductors against photodecomposition processes. In the presence of such cyanometalate layers, the kinetics of interfacial charge transfer are greatly dependent on the nature of intercalated alkali cations. These cations interact not only with the overlayer but also with the semiconductor itself. The effect of specific adsorption by soft cations such as Cs+ and Hg2+ has also been investigated. n- CdS/[Cd(Fe(CN)6]2-/1- interfaces allow for the addition of electroactive species to the electrolyte which provide opportunities to generate useful products using solar energy.
