چکیده
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). The ideality factor n and barrier hight b values were determined from the dark current density-voltage characteristics and found as 2.45 and 0.78 eV, respectively. The device shows photovoltaic behavior with an open circuit voltage of 400 mV, short circuit current of 22.9 A/cm2 and fill factor 0.32 under 2.8 mW/cm2 light intensity.

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...

New diarylmethanofullerene derivatives and their properties for organic thin-film solar cells
A number of diarylmethanofullerene derivatives were synthesized. The cyclopropane ring of the derivatives has two aryl groups substituted with electron-withdrawing and -donating groups, the latter with long alkyl chains to improve solubility in organic solvents, an important property in processing cells. First reduction potentials of most derivatives were less negative than that of [6,6]-phenyl...
