The self-assembly on soft interface is a well-known procedure for creating highly ordered films of nanoparticles (NPs) [1]. Assembling metallic nanoparticles that possess surface plasmonic resonance (SPR) can lead to dif-ferent practical applications: from energy conversion devices, such as solar cells, to smart window, the transparency of which being driven by an electric field. As recently published [2], we reported a major enhancement of the photocur-rent in system comprising an aqueous photo-sentisitizer ZnTPPc (0.1 mM) and an lipophilic electron donor Fc (1 mM) in the presence of an interfacial gold film formed by the self-assembly of citrate covered Au NPs [3] promot-ed by addition of methanol at the DCE/water interface. In this case, illumina-tion of the system was at 442 nm to excite both the senstisizer and the gold film. Here, we have investigated photocurrents at different wavelengths - 460, 525, 590 and 660 nm. For this purpose, the electrochemical cell shown in Fig.1 was used.
