| 英文摘要 | In the case of bulk heterojunctions (BHJs) of regioregular poly(3-hexylthiophene) (P3HT) and the soluble fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), electrical properties have been studied based on the Raman spectroscopy. Significantly, a well enough noteworthy phenomenon is the return-back shift of the Raman signal at the 1450 cm-1 with increasing annealing temperature, which was first observed using the normal Raman spectroscopy of the BHJ system. Based on the Herzberg-Teller coupling term in the organic-organic system, the return-back shift may be due to the charge transfer (CT), resulting in the significant change of resistivity (). More importantly, the low annealing temperature-dependent frequency shift (N) is carefully investigated with , and (-N)2. In addition, the connection between Raman intensity and is also established. This study is unprecedented to establish a clear connection between frequency shift and electrical properties, indicating that the Raman technique opens an avenue to analyze the electrical properties and characterize the performance of the battery. |
