Abstract
In the present work, we studied a conjugated phenylenevinylene oligomer containing quinolines and ferrocene (2FcQF1C) as end groups. The optical properties were analyzed by UV-vis and fluorescence spectroscopy. The energies of the Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO) were calculated by the oxidation/reduction potentials obtained by cyclic voltammetry in solution. A prototype of photovoltaic device was realized using a mixture 2:3 w/w of the oligomer (2FcQF1C) with the commercial [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) with a typical configuration of ITO/2FcQF1C:PCBM/Al. Current density-voltage (JV) curves were obtained in dark and using a laser at λ = 405 nm as illumination power source. Preliminary values of conversion efficiencies around of 10−4 % were obtained. These results are promising for optimization studies of the cells.
