Abstract:

The gel polymer electrolytes(GPEs) based on poly (vinylidence fluoride)(PVDF)／a crylate interpenetrating polymer network(IPN) are prepared. The microphase separation type GPEs are characterized by Fourier transform infrared(FTIR) spectroscopy, scanning electron microscope(SEM), respectively. Moreover, the conductivity and the vo ltagecurrent curves of the electrolytes are measured by electrochemical works t ation. The higher porosity and electrolyte uptake are observed in the membranes prepared at lower crosslinker concentration. The suitable crosslinking a crylate monomer improves the porosity and the electrochemical beha vior of GPE. A dyesensitized solar cell(DSSC) employing PGE based on PVDF／pol y(ethylene glycol dimethacrylate) (PEGDMA) IPN yields an opencircuit voltage of 0674 V, shortcircuit current of 8476 mA·cm-2〖ＫＧ４〗and the con version efficiency of 2710％ under 100 mW·cm－２〖ＫＧ４〗illuminatio n.
