Abstract: | 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. |
