Photoelectric Responses of KBiFe2O5.

(a) J-V curves in the dark and under UV illumination at room temperature. Inset shows the measurement setup schematically. (b) Zero-voltage photocurrent density following on-off UV exposure. (c) Open-circuit photovoltaic voltage following on-off UV exposure. (d) Photocatalytic decoloration of methylene blue (MB) under visible light with (lower) and without (upper) KBiFe2O5 powders. Inset: color evolution of MB at corresponding irradiation time.
