Figure 5From: Current-voltage characteristics in macroporous silicon/SiOx/SnO2:F heterojunctionsFit on J-V characteristic of PS/Ox/FTO. Fit of characteristic J-V of PS/Ox/FTO on the same experimental data in Figure 3 with the model proposed in Figure 4 (Equation 3). Light intensity increases in the arrow direction ranging from dark to 110 mW/cm2. All parameters obtained in the dark case are used in the illuminated cases fitting only the photocurrents Il 1and Il 2.Back to article page
