The Ag wire was synthesized by using poly reduction method in glycerol. PVP were employed as a structure-directing agent for the preparation of one dimension silver structure. By using microwave, the uniform morphology of Ag wire could be obtained easily. In order to apply for working electrode of DSSCs, the core-shell structured Ag@TiO2 wire was prepared with 2-mercaptoethanol as a chemical binder by using solvothermal synthesis. The prepared cell with Ag@TiO2 working electrode was indicated higher conversion efficiency than that of standard cell due to the increase of JSC and reduction of recombination rate attributed to high electron mobility of Ag wire. The characterizations were performed by using FE-SEM, TEM, EDX, UV-vis spectroscopy, I-V characteristics. |
