Manual assembly of nanocrystals for enhanced photoelectrochemical efficiency of hematite film

Abstract

To improve the optoelectronic properties of hematite film as a photoanode, hematite film was orientated on the (012) plane by the secondary growth of organized microcrystals. The resultant film showed promising photoelectrochemical effects compared with a randomly oriented one, with a maximum photocurrent of 0.8 mA cm-2 at 1.23 V vs. RHE under the illumination of 1 sun.
