摘要： Materials that contain liquid are deposited into grooves upon a surface of a work piece, such as a silicon wafer to form a solar cell. Liquid can be dispensed into work piece paths, such as grooves under pressure through a dispensing tube. The tube mechanically tracks in the groove. The tube may be small and rest at the groove bottom, with the sidewalls providing restraint. Or it may be larger and ride on the top edges of the groove. A tracking feature, such as a protrusion, Non-circular cross-sections, molded-on protrusions and lobes also enhance tracking. The tube may be forced against the groove by spring or magnetic loading. Alignment guides, such as lead-in features may guide the tube into the groove. Restoring features along the path may restore a wayward tube. Many tubes may be used. Many work pieces can be treated in a line or on a drum.
摘要翻译：含有液体的材料沉积在诸如硅晶片的工件的表面上的凹槽中，以形成太阳能电池。液体可以分配到工件路径中，例如通过分配管的压力下的槽。管子在凹槽中机械地跟踪。管可以小并且在槽底部搁置，其中侧壁提供约束。或者它可能更大并且骑在凹槽的顶部边缘上。跟踪特征，例如突起，非圆形横截面，模制突起和凸角也增强跟踪。管可以通过弹簧或磁负载而被迫力抵靠凹槽。诸如引入特征的对准引导件可以将管引导到凹槽中。沿着路径还原功能可能会恢复一个顺从的管。可以使用许多管。许多工件可以在一条线或一个鼓上进行处理。

摘要： Semiconductor photovoltaic cells have surfaces that are textured for processing and photovoltaic reasons. The absorbing regions may have parallel grooves that reduce loss of solar energy that would otherwise be lost by reflection. One form of texturing has parallel grooves and ridges. The cell also includes regions of metallization for collecting the generated electrical carriers and conducting them away, which may be channels. The topography is considered during production, using a process that takes advantage of the topography to govern what locations upon will receive a specific processing, and which locations will not receive such a processing. Liquids are treated directly into zones of the cell. They migrate throughout a zone and act upon the locations contacted. They do not migrate to other zones, due to impediments to fluid flow that are features of the surface texture, such as edges, walls and ridges. Blocking liquid may also be deposited and migrate within a zone, to block or mask a subsequent activity, such as etching.
摘要翻译：半导体光伏电池具有纹理的表面用于处理和光伏原因。吸收区域可以具有平行的沟槽，其减少否则将被反射损失的太阳能损失。一种形式的纹理具有平行的凹槽和脊。电池还包括金属化区域，用于收集所产生的电载体并使其远离，这可以是通道。在生产期间考虑地形，使用利用地形的过程来管理将接收特定处理的位置，以及哪些位置将不会接收到这样的处理。将液体直接处理到细胞的区域。他们迁移到整个区域，并对所联系的地点采取行动。它们不会迁移到其他区域，因为阻碍流体流动，这是表面纹理的特征，例如边缘，壁和脊。封闭液体也可以沉积并在区域内迁移，以阻挡或掩盖随后的活动，例如蚀刻。
