Dye‐Sensitized TiO₂ Nanotube Solar Cells: Rational Structural and Surface Engineering on TiO₂ Nanotubes

Abstract

Owing to well-defined structural parameters and enhanced electronic properties, highly ordered TiO(2) nanotube arrays have been employed to substitute TiO(2) nanoparticles for use in dye-sensitized solar cells. To further improve the performance of dye-sensitized TiO(2) nanotube solar cells, efforts have been directed toward the optimization of TiO(2) photoanodes, dyes, electrolytes, and counter electrodes. Herein, we highlight recent progress in rational structural and surface engineering on anodic TiO(2) nanotube arrays and their effects on improving the power conversion efficiency of dye-sensitized TiO(2) nanotube solar cells.

High‐Performance Cobalt Selenide and Nickel Selenide Nanocomposite Counter Electrode for Both Iodide/Triiodide and Cobalt(II/III) Redox Couples in Dye‐Sensitized Solar Cells

“…[1][2][3][4][5][6] Typically, a DSSC consists of a dye-sensitized nanocrystalline TiO 2 semiconductor electrode, a counter electrode (CE), and an electrolyte containing a redox couple. The redox couple in the electrolyte regenerates the dye on photoanode back to ground state and is reduced at counter electrode.…”

Integration of individual TiO2 nanotube on the chip: Nanodevice for hydrogen sensing

“…The high interest in titanium dioxide or titania has been stimulated for decades by a myriad of applications of this versatile material such as heterogeneous catalysis, photocatalysis, solar cells, chemical sensors, corrosion‐protective coatings, biomedicine etc. . Over the last few years, increased attention has been paid to the study of nanostructured TiO 2 layers and membranes fabricated by anodic oxidation of pure titanium foils .…”

Electrochemical methods for the characterization and interfacial study of dye-sensitized solar cell

“…Over this period, many new materials have been designed and synthesized to be used to improve the efficiency of DSSC. These include semiconductor oxides, organic sensitizers, redox couples and electrocatalysts for counter electrodes, all of which have been extensively reviewed elsewhere [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In particular, various theoretical studies have also been conducted to elucidate the fundamental processes taking place in DSSC [18][19][20][21][22][23][24].…”
