ABSTRACT We have carried out the characterization of dye-sensitized solar cell (DSSC) using various techniques including current-voltage characteristic measurements, scanning electron microscopy (SEM), atomic force microscopy (AFM), UV-visible spectrophotometry, energy dispersive X-ray (EDX) spectroscopy and X-ray Diffraction (XRD), etc. The result we obtained from our work has clearly shown that dye adsorption capability of the DSSC is affected by ...

Ionization of Metastable 2P-State Hydrogen Atoms by Electron Impact for Coplanar Asymmetric Geometry

Nahar Affiliation(s) Department of Mathematics, Chittagong University of Engineering and Technology, Chittagong, Bangladesh . ABSTRACT The triple differential cross-sections of First Born approximation have been calculated for ionization of metastable 2P-state hydrogen atoms by electron impact in the asymmetric coplanar geometry. In this study a multiple scattering theory of ionization of hydrogen atoms is used. The latest results of the present method are compared with other calculations. It will be added for new experimental study of ionization of hydrogen atoms in their metastable s...
