Aluminum Doped Zinc Oxide (AZO) produced by radio frequency (RF) magnetron sputtering is thought to be the prospective replacement of the de facto standard indium tin oxide (ITO) anode in organic solar cells. In order to achieve a proper resistivity and transmittance of AZO thin film compared to ITO, a systematic study was done to optimize the sputtering conditions. In this work, two primary parameters: target-substrate distance and sputtering power, were optimized, and a optimized film thickness was determined. A poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) bulk-heterojunction organic solar cell was fabricated based on the optimized parameters and the power conversion efficiency reached 0.83%. A theoretical analysis is given to explain the optimization process. This work provides a clear pathway to substitute AZO for ITO in organic solar cells for future mass production.
