(a) Current-voltage characteristics of PVDs containing Au (red), Ag (blue) and Ag/Au (1:1) alloy NPs (olive) and the control device without metal NPs (SLG: black), under 100 mW cm−2 broadband visible (>420 nm) irradiation. The inset shows the device structure with different metal NPs. (b) Corresponding IPCE spectra of the devices in Fig. 4(a). The inset shows the light-harvesting efficiency (LHE) spectra of Au, Ag and Ag/Au (1:1) alloy NP films.
