    • In a module of photovoltaic cells, a method of forming the module interconnects includes a single cutting process after the deposition of all active layers. This simplifies the overall process to a set of vacuum steps followed by a set of interconnect steps, and may significantly module quality and yield. According to another aspect, an interconnect forming method includes self-aligned deposition of an insulator. This simplifies the process because no alignment is required. According to another aspect, an interconnect forming method includes a scribing process that results in a much narrower interconnect which may significantly boost cell efficiency, and allow for narrower cell sizes. According to another aspect, an interconnect includes an insulator layer that greatly reduces shunt current through the active layer, which can greatly improve cell efficiency.
    • 在光伏电池的模块中,形成模块互连的方法包括在沉积所有有源层之后的单个切割工艺。 这将整个过程简化为一组真空步骤,随后是一组互连步骤,并且可以显着地模块质量和产量。 根据另一方面,互连形成方法包括绝缘体的自对准沉积。 这简化了过程,因为不需要对齐。 根据另一方面,互连形成方法包括划线过程,其导致更窄的互连,其可以显着提高电池效率,并且允许更窄的电池尺寸。 根据另一方面,互连包括绝缘体层,其大大减少了通过有源层的分流电流,这可以大大提高电池效率。
