FIG. 1.

SEM image of a film containing P3HT/RB:CNT. The concentration of CNT in rose bengal (RB) is 17% by weight.

FIG. 2.

(Color online) Absorption spectra of P3HT, RB:CNT, and P3HT/RB:CNT (17%) films on quartz.

Image of FIG. 3.
FIG. 3.

(Color online) Current-voltage characteristics of four devices under dark and white light illumination. Open symbols represent the dark current of the corresponding devices.

Image of FIG. 4.
FIG. 4.

(Color online) Current-voltage characteristics of a device based on P3HT/RB:CNT (17%) films under dark and white light illumination. Measurements were carried out before and after switching of rose bengal. Inset shows a magnified view of the characteristics in the fourth quadrant.

Image of FIG. 5.
FIG. 5.

Current-voltage characteristics of a device based on P3HT/RB:CNT (17%) films under dark and different illumination intensities (as specified in the figures) (a) before and (b) after switching of rose bengal (RB).

Image of FIG. 6.
FIG. 6.

Illumination intensity dependence of current density at before and after conductance switching of rose bengal (RB). The device is based on P3HT/RB:CNT (17%) films. The lines are best fit to the points in the low and high intensity regions.
