چکیده

A microwave hydrothermal reaction of colloidal titanates is presented as a cost-effective synthesis to produce TiO(2) single nanocrystals. The photoelectrode consisting of anisotropic nanorods and V-shaped twins has a significant advantage for achieving an appreciable incident photon-to-current conversion efficiency of 85.6% for the dye-sensitized solar cell.

Synthesis of TiO2 nanorods with a microwave assisted solvothermal method and their application as dye-sensitized solar cells

Inthiswork, Titanium dioxide (TiO2) nanostructures have beensynthesized via amicrowave assisted solvothermalmethod using titanium tetraisopropoxide (TTIP),polyvinylpyrrolidone(PVP) and Ascorbic Acid (AA) in ethanol. The mole ratio ofPVP/AA was found to be critical in determining the morphology and crystal phaseof the final product. PVP/AA mole ratio varied from 1 up to 1...

Synthesis and Application of Two Organic Dyes Based on Indoline in Dye-Sensitized Solar Cells

In this paper we sensitized two new organic days dye 1 and dye 2 based on thioindigo with phenothiazine as the electron donor group. We used acrylic acid and cyanoacrylic acid as the electron acceptor anchoring group in dye 1 and dye 2 respectively. The proposed dyes were sensitized from phenothiazine as the starting material by standard reactions and characterized by different techniques such ...

Synthesis and characterization of Ag-doped TiO2 nanostructure and investigation of its application as dye-sensitized solar cell

A new strategy for enhancing the efficiency of TiO2 dye-sensitized solar cells (DSSCs) by doping foreign ion into TiO2 lattice via sol-gel process is reported. DSSCs are based on a semiconductor (i.e., TiO2), formed between a photo-sensitized anode and an electrolyte. In order to reach high conversion efficiency, it is important to increase the electron injection and optical absorption. One pro...

Application of azo dye as sensitizer in dye-sensitized solar cells

An azo dye used as photosensitizers in Dye-sensitized solar cells DSSCs. Azo dyes economically superior to organometallic dyes because they are color variation and cheap. The spectrophotometric evaluation of an azo dye in solution and on a TiO2 substrate show that the dye form J-aggregation on the nanostructured TiO2 substrate. Oxidation potential measurements for used azo dyes ensured an energ...
