Synthesis, characterization and photoelectrochemical properties of polyindole-CdTe hybrid material
چکیده انگلیسی

Polyindole-CdTe (PIN-CdTe) films were prepared by electropolymerization of indole on Pt electrode followed by electrodeposition of CdTe. The synthesized composites were characterized by Raman spectra, UV-vis absorption spectra and SEM images. Photoresponses and photostability of Pt/PIN-CdTe electrodes were determined in polysulphide solution and compared with results obtained for CdTe electrodes without polymer. It was found, that the photocurrent for Pt/PIN-CdTe electrodes is nearly two fold higher and more stable than for Pt/CdTe electrodes. Raman spectra recorded after photo measurements in polysulphides revealed CdS formation. Energy dispersive X-ray spectra (EDS) indicated that amount of CdS formed was higher for CdTe deposits without polymer.
