We report silver-chromate (Ag2CrO4, ACO) as absorber for all-oxide photovoltaics. ACO is known for photocatalysts, but this is the first demonstration of a solar cell using ACO as the absorber. ACO is deposited using pulsed laser deposition. Material characterization shows that under optimum conditions, high-quality polycrystalline films of ACO can be deposited. Schottky junction device with a lateral Al/ACO/Au structure shows diode-like characteristics with an ON/OFF ratio of > 1000. Under AM1.5 illumination, the unoptimized cell shows an open circuit voltage of 0.2 V, which is significant for all-oxide photovoltaics.
