    Abstract: The present invention provides strategies for improving the adhesion among two or more of transparent conducting oxides, electrically conductive grid materials, and dielectric barrier layers. As a consequence, these strategies are particularly useful in the fabrication of heterojunction photovoltaic devices such as chalcogenide-based solar cells. When the barrier is formed and then the grid is applied to vias in the barrier, the structure has improved moisture barrier resistance as compared to where the barrier is formed over or around the grid. Adhesion is improved to such a degree that grid materials and dielectric barrier materials can cooperate to provide a hermetic seal over devices to protect against damage induced by environmental conditions, including damage due to water intrusion. This allows the collection grids to be at least partially exposed above the dielectric barrier, making it easy to make electronic connection to the devices.

    Abstract: The present invention provides nonionic surfactants, compositions incorporating these surfactants, and related methods of making and using such surfactants and compositions. The nonionic surfactants demonstrate excellent equilibrium and dynamic surface tension properties as well as excellent wetting properties. Further, representative embodiments of the surfactants have shown low foaming characteristics, indicating that the surfactants would be suitable in applications where resistance to foaming is desired. The surfactants can be used singly or in combination with other nonionic and/or ionic surfactants as desired. As an over view, the nonionic surfactants of the present invention have a structure in which the surfactant backbone includes one or more amine moieties. At least one, preferably two or more branched, cyclic, fused cyclic, and/or spyro hydrophobic moieties are pendant from at least one of the amine moieties. Additionally, at least one, preferably two or more hydrophilic moieties, preferably alkylene oxide (i.e., polyether) chains also are pendant from at least one of the amine moieties.
