Abstract

To enhance the light harvesting capability of perovskite solar cells (PSCs), TiO ₂ nanoparticles/nanotubes (TNNs) were incorporated into the active layer of PSCs. The TNN-containing cells showed a substantial increase in photocurrent density (J _SC ), from 23.9 mA/cm ² without nanotubes to 25.5 mA/cm ² , suggesting that the TiO ₂ 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 TiO ₂ nanoparticles in the active layer (14.16%), the TNN-containing cells with optimal loading of 9 wt % TiO ₂ nanotubes showed a high PCE of 15.34%.
