(a) IPCE curve for 0.1% Si-doped Fe2O3 measured at 0.4 V versus Ag/AgCl. (b) Momentary and integrated solar photocurrent of the sample obtained by multiplying IPCE with the photon flux spectrum of AM1.5 sunlight. When correcting for the actual experimental intensity of 80 mW/cm2, an integrated photocurrent of 0 . 6 7 mA/cm2 is obtained.
