    • 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。

    • The present invention relates to configuring and wiring together cells in TF PV modules. According to one aspect, cells are fabricated on one plane on a top surface of a substrate, with wiring patterned on a parallel plane, and vias formed to provide connections between the cell plane and wiring plane. In one embodiment, the wiring plane is on the back surface of the substrate and vias are formed through the substrate. In another embodiment, the wiring plane is on the top surface of the substrate underneath the cell plane and an insulating layer, with the vias formed through the insulating layer. In another embodiment, the cell plane formed on the top surface includes superstrate cells that are illuminated through a transparent substrate, with an insulator between the cell plane and an upper wiring plane. According to another aspect, the heavy bus bar connections in the wiring plane can carry large currents and do not block light impinging on the cells. According to further aspects, the wiring plane enables use of parallel cell connections that provide immunity to shading, as described above. Moreover, these connections can be wired in a variety of methods, allowing use of series-parallel arrangements so that, for example, local regions could be parallel connected while larger regions series connected.
    • 本发明涉及将光伏组件中的电池配置和接线在一起。 根据一个方面,在衬底的顶表面上的一个平面上制造电池,其中布线在平行平面上图案化,并且形成通孔以提供电池平面和布线平面之间的连接。 在一个实施例中,布线平面位于基板的背面,并且穿过基板形成通孔。 在另一个实施例中,布线平面位于单元平面下方的基板的顶表面和绝缘层,通孔通过绝缘层形成。 在另一个实施例中,形成在顶表面上的单元平面包括通过透明基板照射的透明单元,在单元平面和上布线平面之间具有绝缘体。 根据另一方面,布线平面中的重型母线连接可以承载大电流并且不阻挡撞击电池的光。 根据另外的方面,如上所述,布线平面能够使用提供对阴影的免疫力的并行单元连接。 此外,这些连接可以以各种方式布线,允许使用串并联装置,使得例如局部区域可以并联连接,而较大区域串联连接。
