<p>The manufacture of solar cells is simplified and cost reduced through by performing successive ion implants, without an intervening thermal cycle. In addition to reducing process time, the use of chained ion implantations may also improve the performance of the solar cell. In another embodiment, two different species are successively implanted without breaking vacuum. In another embodiment, the substrate is implanted, then flipped such that it can be and implanted on both sides before being annealed. In yet another embodiment, one or more different masks are applied and successive implantations are performed without breaking the vacuum condition, thereby reducing the process time.</p> |
