FIG. 1.

Representative atomic force micrographs of the surface of indium tin oxide-coated, solvent-cleaned glass substrates (a) before and (b) after CO2 snow cleaning, and (c) the statistics of particle heights for the areas in (a) and (b).

FIG. 2.

(a) Specific series resistance (R s A) and fill factor (FF) for SubPc- (open squares and dashed line), and DPSQ- (solid squares and solid line) based organic photovoltaic (OPV) cells employing a C60 acceptor. (b) Short-circuit current (J SC) and power conversion efficiency (ηp ) for SubPc and DPSQ OPVs with different areas. The same line symbols are used as in (a).

Image of FIG. 3.
FIG. 3.

Dark current density-vs-voltage (J-V) characteristics (data points) for ITO/MoO3 (15 nm)/DPSQ(13 nm)/C60(40 nm)/BCP(8 nm)/Al devices with various active areas. The solid lines indicate fits to the data. Ideality factors in the donor layer (n D) used in the fit are 5 ± 1, 15 ± 2, 10 ± 2, 12 ± 1 and 7.8 ± 0.7 for areas ranging from 0.01 to 6.25 cm2, respectively. Inset: Conceptual illustration of the effects on film morphology resulting from particles on the substrate surface.

Image of FIG. 4.
FIG. 4.

Calculated dark J-V characteristics assuming a specific series resistance of RSA = 50 Ω·cm2 for various values of the saturation current density, J sD. Note that for the two lowest values of J sD, the curves overlap. Inset: Calculated relationship between FF and J sD.
