Characterization of Dye Sensitized CdSe Quantum Dots

Journal Title: GRD Journal for Engineering - Year 2018, Vol 3, Issue 0

Abstract

The generation of dye sensitized solar cell (DSSC) and quantum dot-sensitized solar cells (QDSSCs) is considered as the third generation of the solar cell. Cadmium selenide (CdSe) is commonly used as n-type semiconducting layer for heterojunction thin film solar cells. In the present work, synthesis of nanoparticles of CdSe has been done using chemical precipitation technique. And extract dye from pomegranate fruit as the natural dyes. Co-sensitization by using two or more sensitizers with complementary absorption spectra to expand the spectral response range is an effective approach to enhance device performance of quantum dot sensitized solar cells (QDSSCs). To improve the light-harvesting in the visible/near-infrared (NIR) region, CdSe quantum dots (QDs) was combined with pomegranate dye for co-sensitized solar cells. . The prepared CdSe QDs were characterized by UV–Vis absorption, and PL spectra. The CdSe quantum dots were prepared successfully of size 2.9 nm synthesized used LEEH as a capping agent. The size of nanoparticles in pomegranate dye found to be 8.99nm. The proposed solution have been characterized by, UV-Visible spectra and photoluminescence studies. The size of nanoparticles is estimated from Yu model. When CdSe quantum dots are combined with dye, CdSe shows absorption from 387nm to 530nm.
