METALLIZATION STRUCTURES FOR SOLAR CELLS

Methods of fabricating a solar cell including metallization techniques and resulting solar cells, are described. In an example, forming a first semiconductor region and a second semiconductor region on the back side of a substrate. A first conductive busbar can be formed above the first semiconductor region. A first portion of a second conductive busbar can be formed above the second semiconductor region. A second portion of the second conductive busbar can be formed above the second semiconductor region, where a separation region separates the second portion and the first portion of the second conductive busbar. A third conductive busbar can be formed above the first semiconductor region. A first conductive bridge can be formed above the separation region, where the first conductive bridge electrically connects the first conductive busbar to the third conductive busbar.
