| 摘 要： | Self-assembled(SA)films (PMP,M=Ce^3 or Ce^4 )of 3,4,9,10-perylenetetracarboxylic acid(PTA)on nanocrystalline TiO2 films with Ce^3 or Ce^4 as a bridge were fabricated and characterized with UV-Vis,IR,and XPS synchrotron radiation photoelectron spectroscopy (SRPES) which gave the HOMO energy levels for the SA films.It was shown that thin-layer sndwich-type solar cells based on these SA films possess good properties for photoelectric conversion.While PTA-loaded TiO2 electrode(P) generated 26.9?f incident monochromatic phototo-to-electron conversion efficiency (IPCE),PMP-sensitized TiO2 electrodes yielded 55.8?and 39.1?for Ce^4 and Ce^3 respectively.PMP films can be considered as a kind of complexes whose HOMO energy levels were proved to eb higher than that of film P,which is one of the major reasons for the increase in IPCE form film P to film PMP.
