Silver layers single-layer devices

In single-layer devices, the emitter layer was fabricated by the dip coating of the polymer layer. Dichloroethane solutions containing PVK, having a molecular weight of 150,000 purchased from Kanto chemical Ltd., and several dopant dyes were prepared and dip coated onto an ITO coated glass substrate. The thickness of the PVK layer was ca. 1000 A. Then, a magnesium and silver cathode was codeposited. 

Anisotropic adhesives are more sensitive than isotropic conductive pastes to the coplanarity of the connecting pads and leads of the substrate and the device because many of them are based on the single-particle bridging concept. The typical properties of a screen-printable isotropic conductive adhesive paste are a silver content of 70-75% by weight, a viscosity of about 80 Pa s, and a curing time of 15 s at 175°C. This fast cure cycle produces an adhesive layer with Tg...
