To enhance the light harvesting capability of perovskite solar cells (PSCs), TiO₂ nanoparticles/nanotubes (TNNs) were incorporated into the active layer of PSCs. The TNN-containing cells showed a substantial increase in photocurrent density (), from 23.9 mA/cm² without nanotubes to 25.5 mA/cm², suggesting that the TiO₂ nanotubes enhanced the charge conduction and harvested more sunlight, which was attributed to the Mie scattering effect. Compared to the power conversion efficiency (PCE) of TiO₂ nanoparticles in the active layer (14.16%), the TNN-containing cells with optimal loading of 9 wt % TiO₂ nanotubes showed a high PCE of 15.34%.
为提高钙钛矿太阳能电池（PSC）的光捕获能力，将二氧化钛纳米颗粒/纳米管（TNN）掺入PSC的活性层中。含TNN的电池的光电流密度（）显著增加，从不含纳米管时的23.9 mA/cm²增至25.5 mA/cm²，这表明二氧化钛纳米管增强了电荷传导并捕获了更多阳光，这归因于米氏散射效应。与活性层中二氧化钛纳米颗粒的功率转换效率（PCE）（14.16%）相比，含9 wt%二氧化钛纳米管最佳负载量的含TNN电池显示出15.34%的高PCE。
