چکیده

The fullerene-based derivative phenyl-C61-butyric acid methyl ester (PCBM) has attracted attention as an n-type transistor channel and organic photovoltaic material due to its solution processability, stability, high electron mobility. However, disorder in solution-processed PCBM thin films makes understanding of charge carrier transport mechanisms difficult. We have fabricated PCBM-based field effect transistors improved device performance by reducing trapping at the dielectric–semiconductor interface improving injection. Single-wall carbon nanotubes were successfully integrated into conventional gold electrodes improve injection efficiency. Meyer–Neldel behavior been investigated a study films. Crystallization was observed during measurement. find that carriers hop between molecules mostly amorphous regions from 145 240 K. is facilitated formation more crystallized when samples are heated

Energy level alignment of poly„3-hexylthiophene...: †6,6‡-phenyl C61 butyric acid methyl ester bulk heterojunction

Photoelectron spectroscopy was used to investigate poly 3-hexylthiophene P3HT , 6,6 -phenyl C61 butyric acid methyl ester PCBM , and their blends on various conductive substrates. The study shows a P3HT-rich layer at the top of the P3HT:PCBM blend films. The energy level alignment of the top P3HT changes with the work function of the substrate and the PCBM concentration at the bottom surface of...

Charge separation and fullerene triplet formation in blend films of polyfluorene polymers with [6,6]-phenyl C61 butyric acid methyl ester.

Transient and steady state optical spectroscopies were used to study thin films made from a series of polyfluorene polymers blended with [6,6]-phenyl C61 butyric acid methyl ester (PCBM) in order to determine the influence of polymer ionisation potential on photoinduced charge separation. We find that the energy of the charge separated state DeltaE(CS), given by the energy difference between th...

Fabrication of One-Dimensional Zigzag [6,6]-Phenyl-C61-Butyric Acid Methyl Ester Nanoribbons from Two-Dimensional Nanosheets.

One-dimensional (1D) zigzag [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) nanoribbons are produced by folding two-dimensional ultrathin PCBM nanosheets in a simple solvent process. The unique 1D PCBM nanostructures exhibit uniform width of 3.8 ± 0.3 nm, equivalent to four PCBM molecules, and lengths of 20-400 nm. These nanoribbons show well-defined crystalline structure, comprising PCBM mol...
