“…[1,2] Successful BHJ devices have been fabricated by solution deposition of mixtures of a soluble conjugated polymer and the fullerene derivative [6,6]-phenyl C 61 butyric acid methyl ester (PCBM). Among the commonly used soluble conjugated polymers are poly(phenylene vinylene) (PPV) [3,4] , polyfluorene [5,6] and polythiophene [7] derivatives. By controlling the BHJ nanomorphology, power conversion efficiencies up to 4-5 % have been achieved.…”

Photocurrent generation by charge-transfer (CT) absorption is detected in a range of conjugated polymer: [6,6]-phenyl C 61 butyric acid methyl ester (PCBM) based solar cells. The low intensity CT absorption bands are observed using a highly sensitive measurement of the external quantum efficiency (EQE) spectrum by means of Fourier-transform photocurrent spectroscopy (FTPS). The presence of these CT bands implies the formation of weak groundstate charge-transfer complexes in the studied polymer:fullerene blends. The effective band gap (E g ) of the material blends used in these photovoltaic devices is determined from the energetic onset of the photocurrent generated by CT absorption. It is shown that for all

“…Photovoltaic cells of a blend of poly(2-methoxy-5-(3¢,7¢-dimethyloctyloxy)-p-phenylene vinylene) (MDMO-PPV) and [6,6]-phenyl C 61 -butyric acid methyl ester (PCBM) have thereby proven their capacity for solar-cell applications, exhibiting power-conversion efficiencies of around 3 % at the global AM1.5 (air mass 1.5) spectrum. [1,2] In a donor/acceptor organic photovoltaic cell, light absorption results in the formation of excitons that dissociate at the heterojunction interface by an ultrafast electron transfer from the donor to the acceptor (sub-picosecond range). [3,4] By aide of an internal electric field, the photogenerated free holes and electrons are subsequently transported through the donor and acceptor phases to the anode and cathode, respectively, resulting in an external photocurrent density j ph .…”

Abstract:In the work reported here, we investigated the interaction between the semiconducting polymer MDMO-PPV and antibodies against the fluorescent dyes FITC and Cy5. The antibodies are adsorbed physically onto thin polymer films on gold electrodes, as seen in AFM images of these films. By tuning the antibody concentration, the contact angle of distilled water with the film can be made to vary between 95° and 50°, showing that different surface densities of antibody can be obtained. That these biosensor films specifically bind their antigenic fluorescent molecules from PBS buffer solution is demonstrated by confocal fluorescence microscopy. Specific antigen-antibody recognition is demonstrated by lack of crosssensitivity between the two antibodies and their antigens. In a biosensor prototype based on differential impedance spectroscopy, these polymer films show a clear response to 1 ppb antigen solution, with a time constant of 2 to 3 minutes.
