  • Patent number: 8569099
    Abstract: Semiconductor photovoltaic cells have surfaces that are textured for processing and photovoltaic reasons. The absorbing regions may have grooves that reduce loss of solar energy that would otherwise be lost by reflection. One form of texturing has grooves and ridges. The cell also includes metallizations for collecting 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 will receive a specific processing, and which locations will not. Liquids are treated directly into zones. They migrate throughout a zone and act upon the locations contacted. They do not migrate to other zones, due to impediments to flow, such as edges, walls and ridges. Liquid may also be deposited and migrate within a zone, to block or mask a subsequent activity, such as etching.
