Nanostructured Hybrid Solar Cells: Dependence of the Open Circuit Voltage on the Interfacial Composition

Nanostructured amorphous titanium suboxide electrodes are 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 is found that a combination of electrode geometry and active layer processing influences the open circuit voltage in these devices.
