Photoanode modified with nanostructures for efficiency enhancement in DSSC: a review

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

“…As we all know, as an important component of quantum dot sensitized solar cells (QDSSCs), the photoanode provides a stable support for quantum dots and an effective way for photogenerated electrons to transfer to external circuits. [18][19][20] Therefore, the preparation of a photoanode with excellent catalytic activity, excellent conductivity and high mechanical stability can effectively improve the photoelectric conversion efficiency (PCE) of the cells. An excellent and effective photoanode should have the following characteristics: the material should have a large specific surface area, and the band gap between the quantum dot sensitizer and the photoanode material should be highly consistent in order to realize the introduction and transport of photogenerated electrons.…”

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

“…The active development and utilization of new energy have become the most important issues in various countries. [1][2][3] Inexhaustible solar energy has become the first choice to solve energy problems, and in order to make full use of solar energy, photovoltaic devices came into being. [4][5][6][7] Quantum dot sensitized solar cells (QDSSCs), as a representative of the third generation of solar cells, are a new photoelectric conversion device.…”

Enhancing Efficiency in Dye-Sensitized Solar Cells: Incorporation of Cu3VSe4 Nanocrystals into TiO2 Photoanodes

“…Although all the components of DSSCs contribute collectively to improving the PCE, the nanostructured mesoporous semiconductor material in photoanodes plays a significant role as an electron transport layer (ETL). 7 It provides a pillar for dye adsorption responsible for incident light absorption, accepting electrons from the excited state of the dye and transporting electrons toward the Pt CE. SnO 2 , Nb 2 O 5 , and so forth, mesoporous TiO 2 (m-TiO 2 ) has been considered as one of the best choices for ETL in DSSCs due to its nontoxic nature, high refractive index, biocompatibility, high transparency toward visible light, chemical and thermal stability, facile synthesis, and low cost.…”

“…Despite DSSC's maturity, its highest certified power conversion efficiency (PCE) stands at only 13% and depends on the following factors: (1) light absorption efficiency, (2) charge injection efficiency, and (3) charge collection efficiency. Although all the components of DSSCs contribute collectively to improving the PCE, the nanostructured mesoporous semiconductor material in photoanodes plays a significant role as an electron transport layer (ETL) . It provides a pillar for dye adsorption responsible for incident light absorption, accepting electrons from the excited state of the dye and transporting electrons toward the Pt CE.…”
