Photoelectrochemical Studies of P3CT Modified CdSe Nanorod Composite Film Electrode

Hao Yan

Abstract

CdSe nanorods(zinc blende and wulitize) were prepared via hydrothermal method.The CdSe nanorod was formed with a diameter about 100 nm and a length about 300 nm.The photoelectrochemical pro-perties of the CdSe nanorods/P3CT composite film electrode were investigated.The results show that the maximum value of photocurrent appeared at an electrode potential of-0.6 V.The maximum IPCE(13.5%) of the modified film electrode was lower than that of 17.7% CdSe nanorord film electrode.The p-n heterojunction was existed in the CdSe/P3CT composite film electrode.Because of the existence of p-n heterojunction,under certain condition the IPCE of P3CT modified CdSe nanorod was larger than that of CdSe film electrode in the whole long wavelength region(410 nm).
