Abstract

The preparation and characteristics of ZnO(Zinc oxide) co-sputtered TaO (Ta oxide) electrodes(ZTO) grown on glass substrates using a specially designed composite target for use in organic solar cells are described. It was found that both the electrical and optical properties of the ZTO films were critically dependent on the Ar/O2 flow ratio and sputtering power. In addition, all ZTO electrodes show amorphous structure regardless of the Ar/O2 flow ratio, due to the low substrate temperature. We obtained the ZTO electrode with sheet resistance of 30 Ohm/square and average optical transmittance of 80% in room temperature. The conversion power efficiency by using ZTO electrode at optimized conditions is 2.6 %.
