Photosensitization of TiO2 nanorods with CdS quantum dots for photovoltaic devices

Photocurrent enhancement of the CdS/TiO 2 /ITO photoelectrodes achieved by controlling the deposition amount of Ag 2 S nanocrystals

“…In photovoltaic applications, quantum dot (QD)-sensitized photoelectrodes have been widely investigated due to their importance in light absorption and charge transfer [1][2][3][4][5][6][7][8]. The photoelectrodes are typically TiO 2 films due to their non-toxic property and outstanding chemical stability [9].…”

The fabrication of SnSe/Ag nanoparticles on TiO2 nanotubes

“…Importantly, the technology to deposit Ag nanoparticles is simple and efficient. On the other hand, compared with CdS [16], CdSe [17], PbS [18,19] and CdTe [20,21], SnSe has a lower band gap (0.9 and 1.3 eV), which makes it an alternative material for a variety of photovoltaic devices [22]. Recently, some researchers focused on modifying the nanotubes with two or more nanoparticles, such as CdS/CdSe/ZnS [23] and CdS/CdSe [24] to improve the photosensitivity of TiO 2 NT.…”

Photocatalytic degradation of gaseous benzene with CdS-sensitized TiO2 film coated on fiberglass cloth

“…To date, CdS prepared by S-CBD process has been successfully served as a good sensitizer to sensitize TiO 2 films. Chen et al [18] presented that the CdS quantum dots sensitized TiO 2 nanorod arrays thin film electrodes had a significant improvement on the energy conversion efficiency. Xie et al [14] prepared CdS quantum-dots-sensitized TiO 2 nanotube arrays through the sonication-assisted S-CBD technique.…”

“…To improve the photocatalytic efficiency under sunlight, many studies are attempted to extend the absorption spectrum to the visible light range, such as doping with non-metals (such as N) [13], or coupling with low band gap semiconductors (such as CdS and CdSe) [14][15][16][17][18][19]. In these approaches, coupling TiO 2 with the inorganic semiconducting materials is known as a promising option.…”
