文摘

Triple-layered photoanode was developed for efficient dye-sensitized solar cells. 0-D TiO2 nanoparticles (TNPs) and 1-D open-ended TiO2 nanotube arrays (TNTs) were used. 2-D β-NaYF4:Er3+, Yb3+@SiO2@TiO2 was employed as a scattering and upconverting layer. Effect of TNT thickness on electron transport rate was studied. Short-circuit current density of 17.47 mA cm–2 and efficiency of 9.11% were achieved.
