New generation synthesis of nanomaterials for dye sensitive solar cells, characterization and applications

In this study, we report the development of monodisperse Pt nanomaterials deposited on functionalized multiwalled carbon nanotube (Pt NPs @ f-MWCNT) and their usage as the counter electrode (CE) in dye-sensitized solar cell (DSSC). Pt NPs @ f-MWCNT nanocomposites was easily and efficiently prepared by using the microwave assistance method. The data displays that the synthesis method is very effective for mono dispersion of Pt NPs on functionalized multi walled carbon nanotubes.. The morphological characterization of Pt NPs @ f-MWCNT was fully characterized by employing several techniques such as XRD, TEM, HR-TEM, Raman and XPS methods. The electro-catalytic performance of Pt NPs @ f-MWCNT has been also assessed by using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements.
