| Annotation | We fabricated and studied the electrical and photovoltaic properties of organic solar cell based on poly (3-hexylthiophene) (P3HT) as an electron donor blended with the acceptor [6, 6]-Phenyl C61-Butyric Acid 3-Ethylthiophene 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. |
