From: Influence of MoO3(110) Crystalline Plane on Its Self-Charging Photoelectrochemical Properties

(a) Current profiles of α-MoO3 thin films (synthesised in 5 wt% H2O) during charging (illumination) and discharging (dark) processes. Applied potential, 1.0 V vs Pt; Electrolyte 0.1 M Na2SO4; UV-illumination source: 300 W Xe lamp. The red dotted line indicates development of the effective dark current during illumination. The area under the discharge curve indicates total amount of charge released in dark and, (b) linear relationship between change storage capacity and XRD I110/I020 peak intensity of α-MoO3 thin films.
