Fig. 9

a SEM image of the layer structure of PSi. Insert shows the three-dimensional arrangement of the microcavity structure. b The reflection spectrum of the PSi before and after functionalization with RC. Arrow indicates the shift in the specific reflection mode after the RC binding. c Light-induced photocurrent with the PSi/RC electrode in the presence of externally added UQ-0 mediator. Traces correspond to the signal during consecutive illumination periods. The measurement was done with the three-electrode electrochemical cell shown in Fig. 7 (Authors are grateful to Dr. G. Palestino (Universidad Autónoma de San Luis Potosí, Mexico) and Dr. Vivechana Agarwal (CIICAP—Universidad Autonoma del Estado de Morelos, Cuernavaca, Mexico) for providing the PSi microcavities for the experiments with RCs.)
