Preparation of CdSe quantum dots using laser ablation technique for dye-sensitized solar cell
Zainab H. Omran1, Odai N. Salman2, A. K. Ali3.
Organic dyes are known to be widely used in the manufacture of dye-sensitized solar cells.
However, theoretical screening does not play an essential role in dyes design. This work seeks
to improve the conversion efficiency of the dye-sensitized solar cells. Clean-laser ablation in
ethanol methodology was used for cadmium selenide quantum dots (CdSe QDs) synthesis. The
morphological and optical characteristics of the prepared CdSe QDs were investigated by X-ray
diffraction, UV-Vis spectra, Fourier Transform infrared spectroscopy; and transmission
electron microscopy photographs. The resultant CdSe QDs has a cubic crystal structure of 4 nm
averaged particle size. The optimum QDs-sensitized solar cell can be gained by attaching the
QDs to a metal oxide nanoparticles (NPs) such as titanium dioxide NPs (TiO2 NPs) by the laser
ablation method as they are non-ligands.
