제목 Dye-sensitized solar cells with SiO2 spheres decorated with tightly assembled silver nanoparticles
초록 We investigated the effects of localized surface plasmon resonance (LSPR) on the dye-sensitized solar cells (DSSCs). SiO2 spheres decorated with tightly assembled silver nanoparticles (SiO2-t-Ag@SiO2) were incorporated into the photoanode of a dye-sensitized solar cell. The photoanode thin films that contain tightly assembled Ag nanoparticles showed higher light absorption and reflectance than thin film composed of only TiO2. By blending 3 wt% of SiO2-t-Ag@SiO2 with TiO2 paste, the power conversion efficiency (η) increased from 5.73% to 6.88%. This improvement was mainly due to a 17% increase in the short-circuit current density (JSC), which was ascribable to plasmon-enhanced light absorption.
