Abstract
In 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 voltage
