Abstract
Abstract Two‐dimensional (2D) Ti 3 C 2 material has a wide range of photovoltaic applications due to its unique electronic, optical, and plasmonic properties. Herein, we present a series of Ti 3 C 2 (0, 0.6, 0.8; wt%) nanosheets‐modified P25 nanoparticles as photoanode films for dye‐sensitized solar cells (DSSCs). The DSSC based on P25 and 0.6 wt% Ti 3 C 2 photoanode achieves a fairly good efficiency (9.22%), which greatly exceeds the counterpart based on the pure P25 (7.16%). Benefiting from high light scattering and metallic electrical conductivity of Ti 3 C 2 additive, the P25/Ti 3 C 2 ‐based DSSC exhibits a superior behavior of controlling photogenerated charge recombination compared with pure P25 one.
