dc.description.abstractIn this thesis, the photovoltaic properties of the blended polymer of APFO-G6 have been investigated based on enhancing its absorbance. The structure of the blended polymer was ITO/PEDOT:PSS/D75:APFO-G6:PCBM/Al. The electrical properties were studied using Current Voltage (J-V) characteristics and Impedance spectroscopy (IS) measurement. The optical absorption spectrum was measured using UV/VIS/NIR Spectrometer. The J-V plot shows the structure has photovoltaic properties.The absorbtion spectrum shows the structure absorbed as needed in the extended visible region of the spectrum. Fill factor and the ef ciency was improved due to increment of absorbance. And according to impedance Spectroscopy measurement, the Cole- Cole plot shows the depletion resistance and capacitance depend on the bias voltageen_US
