| dc.description.abstract | Photovoltaic device based on blend of alternating poly uorene green-6 (APFO Green- 6) and [6,6]-phenyl C61-butyric acid methyl ester(PCBM) in a sandwich structure of ITO/PEDOT-PSS/APFO Green-6:PCBM/Al was fabricated. The device was characterized by analyzing the current density-voltage measurements under dark and illumination as well as by impedance spectroscopy. The observed J-V curve under dark agree well with the trap-controlled space charge limited transport theory. The main solar cell parameters recorded at room temperature under 80mA/cm2 white light intensity are: VOC = 547mV, JSC = 0.314mA/cm2, with power conversion ef- ciency 0.107 %, and ll factor, of 0.5. The complex impedance analysis exhibits a bias voltage dependent whose Cole-Cole plot is a single semicircle. This is modelled by one parallel RC circuit, usually obtained from metal-semiconductor(MS) device | en_US |
