Abstract

Cobalt aluminate-Fe2O3 p-n nanocomposite electrodes were deposited on the silver coated stainless steels and annealed at 800°C. Their photoresponses were investigated and compared with that of p-type Cobalt aluminate. We found that nanocomposite electrodes exhibited much improved photoresponses as compared to p-type Cobalt aluminate. We attribute the improvement to the band offset at the formed three-dimensional p-n junction, which promote photo-generated carrier separation and reduce carrier recombination.
