Fabrication and Characterization of Rose Bengal Sensitized Binary TiO2 -ZrO2 Oxides Photo-electrode Based Dye-sensitized Solar Cell

Abstract

Titanium oxide (TiO) electrode has been the most commonly used photo-electrode for the dye-sensitized solar cells (DSSCs). Several research 2 groups have already reported that only TiO layer is not yet ideal for electron transfer in the absence of space charge layer and also demonstrated 2 the procedures for coating nanocrystalline semiconducting oxide films with a thin overcoat of a different semiconducting oxide with a higher conduction band energy level (E). Zirconium oxide (ZrO) is a suitable material for such overcoat because of its higher E. The binary C 2 C o TiO-ZrO oxide photo-electrodes were prepared by doctor blading technique. The electrodes were annealed at 450 C and then sensitized by 2 2 Rose Bengal (RB) dye. The DSSC fabricated by binary TiO-ZrO photo-electrode showed improved solar energy conversion efficiency than that 2 2 of fabricated only by pure component of TiO .

Synthesis and characterisation of heteroatom-doped reduced graphene oxide/bismuth oxide nanocomposites and their application as photoanodes in DSSCs

“…Various approaches, such as doping, 6 surface modication, 7 and the use of hybrid semiconducting nanomaterials, [8][9][10][11][12] have been proposed to improve the properties of semiconductor materials. Semiconductor nanomaterials such as metal oxides, including titanium dioxide (TiO 2 ), 13 zinc oxide (ZnO), 14 zirconium dioxide (ZrO 2 ), 15 tungsten trioxide (WO 3 ), 16 and tin(IV) oxide (SnO 2 ), 17 have been extensively explored as photoanode materials in DSSCs.…”

Preparation and Mechanical Properties of Copper Matrix Composites Reinforced by Carbon Nanotubes and Al2O3

“…[ 16–18 ] Some studies have shown that many metal oxides such as ZnO, [ 19–22 ] CuO, [ 23 ] NiO, [ 24 ] Fe 2 O 3 , [ 25 ] ZrO 2 [ 26 ] are widely used in various fields as a result of their unique properties. [ 27–31 ] Among them, Al 2 O 3 ceramic particles can effectively improve the strength of copper matrix composites due to their high hardness and wear resistance. So, Al 2 O 3 particles are also a good reinforcing phase of the copper matrix.…”

Flexible Diodes/Transistors Based on Tunable p-n-Type Semiconductivity in Graphene/Mn-Co-Ni-O Nanocomposites

“…There is no leakage of tunneling current base on electronic quantum-tunneling-effect in nanoscale components because of the electron mobile near Dirac point. The development of these new semiconductor composite materials, with inherent flexibility, has broad prospects for the design and manufacture of flexible nanoelectronic components, including design and manufacture of chips, transistors, thermoelectric and Hall components, and sensors [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”
