Experimental dark current of a MDMO-PPV:PCBM device (symbols) and fit to the exponential part (lines) at various temperatures.
Experimental current under illumination of an MDMO-PPV:PCBM device at 295 K (symbols) and the current density predicted by Eq. (2) (line). Inset: The photogenerated current density of an MDMO-PPV:PCBM device (symbols) as a function . The line denotes the short-circuit current density corresponding to the assumption of being constant.
of a MDMO-PPV:PCBM device (symbols) as a function of light intensity, the solid lines denote linear fits to the experimental data, and the dotted line represents the prediction at room temperature of Eq. (12). The inset shows the spectrum of the white light halogen lamp used to illuminate the devices.
