SiO2/TiO2 core/shell nanoparticles (STCS-NPs) with diameters of 110, 240, and 530 nm were fabricated to investigate the influence of the size and refractive index of light-scattering particles on light-scattering properties. The optical properties of STCS-NPs were evaluated and compared with SiO2-NPs and TiO2-NPs. The structure of STCS-NPs, consisting of a low refractive index core and high refractive index shell, provides efficient light scattering. The optimized anode film with STCS-NPs had ca. 20% improved power conversion efficiency (PCE).
制备了直径分别为 110、240 和 530nm 的 SiO2/TiO2 核/壳纳米颗粒（STCS-NPs），以研究光散射颗粒的尺寸和折射率对光散射特性的影响。评估并比较了 STCS-NPs 的光学性质与 SiO2-NPs 和 TiO2-NPs 的光学性质。STCS-NPs 的结构由低折射率核和高折射率壳组成，可提供有效的光散射。具有 STCS-NPs 的优化阳极膜的功率转换效率（PCE）提高了约 20%。
