摘要
The present invention provides strategies for improving the adhesion between a barrier region, a transparent conductive region, and/or an electrically conductive grid through the use of an adhesion promoting region. The adhesion promoting region is optically transmissive and comprises a metal layer, a metal nitride layer, a metal carbide layer, or a combination thereof and preferably comprises at least one of Cr, Ti, Ta, and Zr or a combination thereof. These strategies are particularly useful in the fabrication of heterojunction photovoltaic devices such as chalcogenide-based solar cells. 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. The adhesion promoting region also serves as a barrier to the migration of Na, Li, and the lanthanoid series of elements.
