Abstract

To tailor the Au@Ag@SiO₂ LSPR effect by varying the Ag shell thickness, the Au@Ag@SiO₂ core–ultra-thin shell nanoparticles are fabricated and introduced into DSSC for improving light harvesting and decreasing the recombination of photo-carriers. The Au@Ag@SiO₂ electrode exhibits a photo-conversion efficiency of 23.42% (486.7 nm, 10 mW cm⁻²).
