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...

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...

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...

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...
