Abstract

Nanostructured amorphous titanium suboxide electrodes were fabricated to determine the effects of the electrode geometry on the device performance of poly(3-hexylthiophene): (6,6)-phenyl C61 butyric acid methyl ester inverted solar cells. It was found that a combination of electrode geometry and active layer processing influences the open circuit voltage in these devices.
