The performance of CdS quantum dot sensitized ZnO nanorod-based solar cell

UV‐aided graphene oxide reduction by TiO2 towards TiO2/reduced graphene oxide composites for dye‐sensitized solar cells

“…have been extensively studied for a variety of applications such as catalysis, gas sensors, air purification, solar-to-electric energy conversion, photoelectrochemical systems, and so on. [1][2][3][4] TiO 2 is one among the different semiconductors which has been subjected to extensive research and the chemical stability, position of energy level bands, high optical transmittance in the IR-Visible spectrum and the nontoxicity are some of the important attractive properties of TiO 2. 5 However, when it is used as photoanode in dye-sensitized solar cells (DSSCs), in which it is a thick film (up to 10 μm in thickness) made of TiO 2 nanoparticles, the efficiency of the cell is affected by the recombination of the photogenerated electron hole pairs.…”

“…In recent years, several wide bandgap semiconductors, such as SnO 2 , ZnO, TiO 2 , etc. have been extensively studied for a variety of applications such as catalysis, gas sensors, air purification, solar‐to‐electric energy conversion, photoelectrochemical systems, and so on 1‐4 .
