چکیده
Thin films of a conjugated polymer Poly [2-methoxy-5-(3’,7’-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMO-PPV) were prepared from chloroform, 1,2dichlorobenzene and toluene solutions by spin coating technique on quartz substrates. Absorption and photoluminescence (PL) spectra of the polymer thin films prepared from different solvents were measured. The UV-vis absorption and PL spectra of MDMO-PPV films was affected by solvents used for spin coating. Further, with Atomic Force Microscope (AFM) it has been demonstrated that the surface morphology of MDMO-PPV: [6,6]-Phenyl C61-butyric Acid 3ethylthiophene Ester thin films depends strongly on preparation condition (solvents).

Highly Conductive Bilayer Transparent Conducting Oxide Thin Films for Large-Area Organic Photovoltaic Cells
Highly conductive In-doped CdO/Sn-doped In2O3 (CIO/ITO) bilayer transparent conducting oxide (TCO) thin films were prepared by combining, in sequence, metal-organic chemical vapor deposition (MOCVD) and ion-assisted deposition (IAD) techniques. The bilayer substrates, with a low In content of ∼19 atom % and a low sheet resistance of only ∼4.9 Ω/0, were investigated as anodes in the bulk-heteroj...

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...

We fabricated and studied the electrical and photovoltaic properties of organic solar cell based on poly (3hexylthiophene) (P3HT) as an electron donor blended with the acceptor [6, 6]-Phenyl C61-Butyric Acid 3Ethylthiophene Ester (modified fullerene). The active layer composed of (3:1, w/w) mixture of P3HT and the modified fullerene was sandwiched between indium tin oxide (ITO) and aluminum (Al...
متن کاملCharge 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...
