Figure 7. Photoelectric conversion ability of N1.

(a) Typical anodic current response on irradiation of a working electrode (SnO₂ substrate modified with 36-layer N1) with intermittent 500-nm light. (b) Action spectrum for the photocurrent generation (magenta dots) and absorption spectrum of N1 (black solid line). (c) Control experiment without N1. (d) Control experiment without TEOA. The irradiation pattern is the same as that of a. (e) Relationship between the relative quantum yield (QY) and thickness of N1 on irradiation with 500-nm light. The highest QY (0.86% by single-layer N1) is taken as the standard.
