g-C3N4@TiO2 photoanodes for high-efficiency QDSSCs: improved electron transfer and photochemical stability

“…To further demonstrate the enhancement of photocatalytic performance by the formation of g-C 3 N 4 @TiO 2 composites, we used photoluminescence (PL) spectroscopy to verify the photogenerated carrier separation efficiency. 48,49 The results show that the lower the fluorescence intensity of the material, the higher the photogenerated carrier separation efficiency. Because the TiO 2 material itself has some defects, it will cause the photogenerated carrier and hole composite.…”

Core–shell ZnO@TiO2 hexagonal prism heterogeneous structures as photoanodes for boosting the efficiency of quantum dot sensitized solar cells

“…To further demonstrate the enhancement of the ZnO@TiO 2 heterojunction formation on the photocatalytic performance, PL spectroscopy and photocurrent test were used to verify the photoexcited carrier separation efficiency. 60,61 Due to the uncontrollable factors in the preparation process, there are some defects in the properties of the ZnO surface or the material itself, and the appearance of these defects will lead to photogenerated carrier and hole recombination.
