    摘要： A process for the preparation of polybenzazole filaments which comprises (a) extruding a solution of polybenzazole polymer in a mineral acid through a spinneret having at least 100 holes, which are arranged to form a annular pattern around the center of the spinneret, the center and at least two radial sections of the spinneret having no holes and an average width which is at least about 3 times the minimum pitch of the holes, thereby forming filaments of the polymer solution; (b) drawing the filaments of the polymer solution through a quench chamber while providing a substantially radial gas flow therein across the spinneret from at least two different directions; and (c) washing and drying the filaments of the polymer solution under conditions sufficient to form polybenzazole filaments.

    摘要： 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.

    摘要： Improved protection systems for CIGS-based microelectronic devices of the type incorporating electric conductor(s) such as an electronic collection grid. In one aspect, the present invention relates to a photovoltaic device having a light incident surface and a backside surface. The device includes a chalcogenide-containing photovoltaic layer comprising at least one of copper, indium and/or gallium. A transparent conductive layer is interposed between the photovoltaic layer and the light incident surface, wherein the transparent conductive layer is electrically coupled to the photovoltaic layer. An electronic collection grid is electrically coupled to the transparent conductive layer and overlying at least a portion of the transparent conductive layer. An elastomeric structure having a light incident surface, said structure overlying at least portions of the electronic collection grid and the transparent conductive layer in a manner such that the light incident surface of the elastomeric structure is spaced apart from a major portion of the conductor, and wherein the elastomeric structure comprises an elastomeric siloxane polymer having a WVTR of at least 0.1 g/m2-day. An optional protective barrier overlies the elastomeric structure. The protection systems of the invention incorporate elastomers with water vapor transmission rates that are atypically high in the context of CIGS-based devices.
