Photocurrent-potential (I-V) curves of Ag-doped α-Fe2O3 nanorod films, (A) pristine α-Fe2O3, (B) Ag/Fe-0.005, (C) Ag/Fe-0.01, (D) Ag/Fe-0.05, (E) Ag/Fe-0.1 and (F) Transient photocurrent responses (current density vs. time curves) of Ag-doped α-Fe2O3 nanorod films at 1.0 V vs. Ag/AgCl under simulated solar illumination (AM 1.5G, 100 mW cm−2), following the photocurrent-potential (I-V) measurements shown in Fig. (A–E).
