Anatase TiO2and ITO co-sputtered films for an indium-saving multicomponent electrode in organic solar cells

Publication year: 2011 Source: Solar Energy Materials and Solar Cells, Available online 16 December 2011 Jong-Wook Lim, Seok-In Na, Han-Ki Kim We report the characteristics of a Ti–In–Sn–O (Ti–ITO) multicomponent electrode prepared by co-sputtering of ITO and anatase TiO2targets for reducing high-cost indium content in the anode layer of organic solar cells (OSCs). The dependence of electrical, optical, structural, and surface properties of the Ti–ITO multicomponent electrodes on the RF power was investigated in detail. The optimized Ti–ITO (80 W TiO2co-sputtered ITO) electrode exhibited a low sheet resistance of 18.06 Ω/square, a high average optical transmittance of 80.61% and a root mean square roughness of 2.40 nm.
