Enhanced electron transport through two-dimensional Ti_(3)C_(2) in dye-sensitized solar cells

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.
