“…In addition, it was found that the dye loading capacity of TiO 2{001} decreased with an increase of %S (Figure 1(g)). This result is in contrast to the conventional understanding that the increase of %S can lead to the higher dye absorption capacity [21]. In our work, grain size seems to be more important factor for increasing dye absorption ability.…”

This work developed a novel ternary composite photoanode of dye-sensitized solar cell (DSSC) composed of (i) N-, S-doped titanium dioxide with exposed {001} facet (N-, S-TiO2{001}), (ii) N-, S-doped reduced graphene oxide (N-, S-rGO), and (iii) commercial titanium dioxide (P25). The DSSC device fabricated with the ternary composite photoanode showed the greatest of power conversion efficiency (8.62%) compared to the device fabricated with P25 photoanode (3.20%). This enhancement was attributed to the synergistic effect of the N-, S-TiO2{001} and the N-, S-rGO, which act as an electron enricher and an electron extractor, respectively.

“…So far, there have been a lot of reports on the preparation of anatase TiO 2 with exposed {001} facets via various methods. Most of synthesis methods utilized hydrofluoric acid or fluorine-containing compounds as a capping agent, such as HF, TiF 4 , and NH 4 F. − However, hydrofluoric acid and fluorine-containing compounds are quite toxic and corrosive . More discouragingly, the fluoride ions can passivate the {001} crystal planes and engender the exciton-like trap states, which can restrict the electron mobility .…”

In this work, the hollow rectangular prism-like TiO 2 (HRP-TiO 2 ) mesocrystals with exposed {001} facets were synthesized via an in-situ hydrothermal process without introducing any additional hydrofluoric acid or fluoride-containing compounds. A double-layer structured photoanode based on HRP-TiO 2 mesocrystals (as the light scattering top layer) and TiO 2 nanocrystalline (TiO 2 -NC, as the underlayer) was constructed. The dye-sensitized solar cell (DSSC) based on the double-layer photoanode showed a remarkable efficiency of 9.16%, which was superior to the pure TiO 2 -NC photoanode-based counterpart (8.19%). The efficiency improvement was attributed to the multiple advantages of HRP-TiO 2 mesocrystals with high crystallinity and superior light scattering capability. More importantly, the anatase phase mesocrystals with exposed {001} facets could provide efficient pathway for electrolyte diffusion and electron transport.
