Abstract: Provided are interconnect circuits for interconnecting arrays of battery cells and methods of forming these interconnect circuits as well as connecting these circuits to the battery cells. An interconnect circuit may include a conductive layer and one or more insulating layers. The conductive layer may be patterned with openings defining contact pads, such that each pad is used for connecting to a different battery cell terminal In some embodiments, each contact pad is attached to the rest of the conductive layer by a fusible link formed from the same conductive layer as the contact pad. The fusible link controls the current flow to and from this contact pad. The insulating layer is laminated to the conductive layer and provides support to the contacts pads. The insulating layer may also be patterned with openings, which allow forming electrical connections between the contact pads and cell terminals through the insulating layer.

Abstract: A rear-contact solar cell interconnect is disclosed. The rear-contact solar cell interconnect includes a first conductive foil with an opening and a second conductive foil. The first conductive foil is arranged to be electrically connected to a first polarity contact of a solar cell. The second conductive foil is arranged to be electrically connected to a second polarity contact of the solar cell through the opening of the first conductive foil. The solar cell includes a first surface arranged to receive solar irradiation and a second surface substantially opposite the first surface. The first polarity contact and the second polarity contact are provided on the second surface of the solar cell.
