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)).
为了通过改变银壳层厚度来调整金@银@二氧化硅的局域表面等离子体共振效应，制备了金@银@二氧化硅核-超薄壳层纳米颗粒，并将其引入到染料敏化太阳能电池中，以改善光捕获并减少光生载流子的复合。金@银@二氧化硅电极在486.7 nm、10 mW cm(-2)条件下表现出23.42%的光转换效率。
