Plasma EtchFacility for Printed Organic Electronics

Reactive Ion Etching Plasma like in this equipment from PlasmaEtch is a dry etching technology using a chemically reactive plasma at low pressure. It presents the advantages of being directional, selective, and can make controlled alterations of the material properties. It can be used for the etching of soft and hard thin films for nano- and microstructuring as well as pre-deposition surface...

Solution-Processed p-Dopant as Interlayer in Polymer Solar CellsFacility for Printed Organic Electronics

We report here an original approach to dope the semiconducting polymer–metal interface in an inverted bulk-heterojunction (BHJ) organic solar cell. Solution-processed 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F 4 -TCNQ), is deposited on top of a P3HT:PC 61 BM layer before deposition of the top electrode. Doping of P3HT by F 4 -TCNQ occurs after thermally induced diffusion at 100 °C...

Lanthanum Hexaboride As Novel Interlayer for Improving the Thermal Stability of P3HT:PCBM Organic Solar CellsFacility for Printed Organic Electronics

For efficient organic photovoltaic (OPV) solar cells, a low work function electrode is necessary to enhance the built-in voltage of the active layer, thereby improving the overall efficiency. Calcium is often used for this purpose in the laboratory; however, its development on a larger scale is impaired by its high reactivity with oxygen and water and the resulting low stability of solar cells...

An Alternative Anionic Polyelectrolyte for Aqueous PEDOT Dispersions: Toward Printable Transparent ElectrodesFacility for Printed Organic Electronics

Organic conducting polymers are promising electrode materials for printable organic electronics. One of the most studied conducting polymers is PEDOT:PSS, which is sufficiently conductive and transparent, but which shows some drawbacks, such as hygroscopicity and acidity. A new approach to stabilize PEDOT in aqueous dispersions involves the replacement of PSS with a basic polyanion based on a...

Archimedean Tilings and Hierarchical Lamellar Morphology Formed by Semicrystalline Miktoarm Star Terpolymer Thin FilmsFacility for Printed Organic Electronics

3-Miktoarm star terpolymer architecture provides a window of opportunity in the design of complex “three-colored” patterns at the nanometer scale. Here, thedirected self-assembly (DSA) of 3-miktoarm star terpolymer (poly(1,1-dimethyl silacyclobutane)-arm-polystyrene-armpoly(D,L-lactide acid)) (PDMSB-arm-PS-arm-PLA, noted hereafter 3 ?-DSL) into a hierarchical lamellar morphology is described....

Solution-processed blue phosphorescent OLEDs with carbazole-based polymeric host materialsFacility for Printed Organic Electronics

Abstract A new carbazole-based polymer PEPEK varying from the previously reported PEPK by the length of the spacer between the polymer backbone and the pendent carbazole moiety was investigated as polymeric host for solution-processed devices. Interestingly, if the two polymers are structurally close since the length of the alkyl chain only differs from one carbon atom, the previously reported...
