Quantum Dot (QD) Sensitizer on the Surface of TiO₂Film: Effect of Metal Salt Anions Dissolved in Chemical Bath on the Distribution Density of SILAR-Grown PbS QDs

Counter electrode materials based on carbon nanotubes for dye-sensitized solar cells

“…Other semiconductors have also been applied as photoanode in DSSCs because they possess similar band structure to that of TiO2 and bring their own unique characteristics to the cell. These semiconductors include ZnO [65,66] (extensively studied after TiO2), SnO2 [67], Nb2O5 [68], WO3 [69], Ta2O5 [70], CdSe [71], CdTe [72], CdS [71] and PbS [73] nanostructures. To improve the performance of the photoanode, these nanostructures can be doped with various ions such as Zn 2+ , La 3+ , Nd 3+ , Er 3+ and Ho 3+ and can also be decorated with different noble metals such as silver, chromium, copper, and gold [74][75][76][77][78][79].…”
