Figures

Image of FIG. 1.
FIG. 1.

Overall power conversion efficiency , open circuit voltage , short circuit current , and fill factor (FF) as a function of active layer thickness under illumination.

Image of FIG. 2.
FIG. 2.

Experimental photocurrent density as a function of effective applied voltage under illumination for a device consisting of a active layer (a) and active layer (b). Circles indicate experimental data, solid line indicates fits of the photocurrent, and the dashed line indicatess the predicted space-charge limit using Eq. (1). The arrows indicate fits of the intensity dependence . Inset: current under illumination vs applied voltage .

Image of FIG. 3.
FIG. 3.

Simulation of the potential (anode left, cathode right) through the device at maximum power point under illumination (solid line) and in dark (dashed line) indicating the effects of space charge.

Tables
