染料敏化太阳能电池Pt/NiP/ITO对电极的制备和性能
Preparation and Performance of Pt/NiP/ITO Counter Electrode for DSSC
摘要
Abstract
NiP alloy film was firstly prepared on the surface of the ITO conductive glass substrate by an electroless plating method,and then,the nanoparticles of platinum were electrodeposited on the NiP–plated layer to obtain Pt/NiP/ITO counter electrode used in DSSC.The parameters of Pt electro-deposition on NiP alloy layer were optimized.The influences of NiP alloy structure and Pt loading on the surface morphology and catalytic activity of Pt/NiP/ITO electrode were investigated.The surface morphology of Pt/NiP/ITO electrode was analyzed by atomic force microscopy.The electrochemical performance of Pt/NiP/ITO electrode was characterized by cyclic voltammetry and electrochemical impedance spectroscopy.The photovoltaic performance was evaluated from photocurrent-voltage curves in a single DSSC.The result shows that the NiP alloy deposited on ITO substrate enhances the conductivity and light reflection performance of the counter electrode,and also improves the distribution of Pt particles on the surface of electrode,resulting in that Jscand η of the DSSC are increased by 4% and 11%,respectively.关键词
