| dc.description.abstract | The Theme of this thesis is to characterize polymer based photovoltaic cell using the J-V measurements and impedance spectroscopy. Absorption spectra of pure (neutral) poly[3-(2,5-dioctyle-pheneyl) thiophene](PDOPT) study showed that the optical band gap of this polymer about 2eV, indicating that it is in the range of inorganic semiconductors. The sandwich structure ITO/PEDOT:PSS/PDOPT:PCBM/Al were utilized to fabricate the device. All the devices which are tested in this work, are bulk heterojunction that are composed of the p-type , PDOPT and n-type fullerene derivative, (phenyl-(6,6’)-c61)-butyric acid methyl ester ( PCBM )blend. The J-V measurements under both illumination dark indicated that the typical diode rectification property with rectification ratio 1.5× 103 at ( ±1.8V ) Such a device of blend ratio 1:2 (PDOPT:PCBM) expected to show a photovoltaic behavior with a power conversion efficiency about 0.028 % under 100mWcm−2 | en_US |
