摘要：The present invention provides strategies for improving the adhesion amongtwo or more of transparent conducting oxides, electrically conductive grid materials, and
dielectric barrier layers. As a consequence, these strategies are particularly useful in thefabrication 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, thestructure has improved moisture barrier resistance as compared to where the barrier isformed over or around the grid. Adhesion is improved to such a degree that gridmaterials and dielectric barrier materials can cooperate to provide a hermetic seal overdevices to protect against damage induced by environmental conditions, includingdamage due to water intrusion. This allows the collection grids to be at least partiallyexposed above the dielectric barrier, making it easy to make electronic connection to thedevices.
