文摘

Poly(3-methylthiophene)-cadmium selenide (PMeT-CdSe)-modified electrode was galvanostatically prepared in CH3CN/LiClO4 in the presence of 3-methylthiophene and nanoparticles of CdSe. The synthesized composites were characterized by the UV–vis spectroscopy, scanning electronic microscopy, Fourier Transform infrared spectroscopy (FTIR) and energy-dispersive X-ray (EDX) techniques. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were used to investigate the electrochemical behaviour of the resulting materials. This study showed that the presence of CdSe nanoparticles in the poly(3-methylthiophene) film improves the optical properties of PMeT via a simple preparation method and shows that these films could be used in photoelectrochemical applications such as the photovoltaic cells.
