摘要：
New type counter electrodes comprised of Pt and a metal oxide biphase, Pt-NiO and Pt-TiO2, were prepared by RF magnetron co-sputtering system for use in dye-sensitized solar cells. Transmission electron microscope images confirmed the formation of similar to 3 nm nanosized Pt polycrystalline mixed with metal oxide phase, which has higher active surface area than a conventional Pt electrode. When the Pt-TiO2 counter electrode was used in the cell, the power conversion efficiency was increased up to similar to 1.56 times, compared to conventional devices composed of a Pt electrode under I Sun with air mass 1.5 Global illumination due to its superior electrocatalytic activity and efficient reflection of incident light at the counter electrode.
