    • 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.

    • 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.
    • 本发明提供了改善透明导电氧化物,导电栅格材料和电介质阻挡层中的两种或更多种之间的粘附性的策略。 因此,这些策略在异质结光伏器件如硫族化物基太阳能电池的制造中特别有用。 当形成屏障,然后将栅格施加到屏障中的通孔时,与在栅格上方或栅格周围形成屏障的情况相比,结构具有改善的防潮性。 附着力提高到网格材料和介电阻挡材料可以配合以提供装置上的气密密封以防止由环境条件引起的损坏(包括由于水侵入引起的损坏)的程度。 这允许收集栅极至少部分地暴露在电介质阻挡层之上,使得容易进行到器件的电子连接。
