    Abstract: According to one aspect of the disclosed subject matter, fabrication methods and structures relating to multi-level metallization of solar cells are described. In one embodiment, a back contact solar cell comprises a substrate having a light receiving front side surface and a backside surface for forming patterned emitter and base regions. A first electrically conductive metallization layer is patterned on the backside base and emitter regions. An electrically insulating layer is formed on the first electrically conductive metallization layer and a second electrically conductive metallization layer is formed on the electrically insulating layer. The second electrically conductive metallization layer is connected to the first electrically conductive metallization layer through conductive via plugs formed in the electrically insulating layer.

    Abstract: A back contact solar cell structure having a light receiving frontside and a metallized backside of on-cell patterned base and emitter metallization electrically connected to base and emitter regions on a back contact solar cell semiconductor substrate. A backplane laminate layer made of resin and fibers and having a coefficient of thermal expansion relatively matched to the back contact solar cell semiconductor substrate is attached to the on-cell base and emitter metallization and to portions of the back contact solar cell semiconductor substrate not covered by the on-cell base and emitter metallization.
