Methods and structures for forming a contact region on a solar cell are presented. The solar cell can have a front side which faces the sun during normal operation, and a back side opposite the front side and a silicon substrate. The silicon substrate can include at least one doped region a dielectric layer formed over the doped region. The solar cell can also include a first metal contact, such as an electrolessly plated metal contact, within a contact region through a first dielectric layer and on the doped region. The solar cell can include a printed metal, such as aluminum, formed or deposited on the first metal contact. The solar cell can include a first metal layer having a first metal contact and the first printed metal. The solar cell can include a second metal layer, such as an electrolytically electroplated metal layer, formed on the first metal layer. |
