A Self-Driven p∕n-Fe[sub 2]O[sub 3] Tandem Photoelectrochemical Cell for Water Splitting

Abstract

It is desirable to fabricate self-driven photoelectrochemical cells (PECs) utilizing low cost, low bandgap, and stable materials for efficient splitting of water into hydrogen. We report here the spray pyrolytically fabricated self-driven tandem PECs for photoelectrochemical water splitting. The combination of synthesized by zinc doping using ethanol as the spray solvent and the undoped synthesized using 1-pentanol as the spray solvent generated the self-driven photoelectrochemical cell for water splitting.
