Abstract

Fluorine doped tin oxide (FTO) and aluminum doped zinc oxide (AZO) were systematically investigated as alternatives to indium tin oxide (ITO) for canonical poly(3-hexylthiophene) (P3HT) + [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) polymer bulk heterojunction (BHJ) solar cells. Devices made with FTO performed twice as well as devices made with ITO, establishing FTO as a suitable, low-cost ITO replacement. Ozone treatment was shown to be a critical enabling element for both FTO and AZO. X-ray photoelectron spectroscopy (XPS) and device characteristics were used to explain the effect of ozone treatment and the origin of open circuit voltage.
