Au@SiO 2 @Ag@SiO 2 core–triple shell nanoparticles are fabricated by a wet‐chemical approach and characterized. Each SiO 2 layer is given a special function, which enhances the surface plasmon resonance to improve light harvesting and reduce interfacial carrier recombination in dye‐sensitized solar cells. The photo‐anode with Au@SiO 2 @Ag@SiO 2 obtains an energy conversion efficiency of up to 9.22%.
