    摘要: A method of fabricating a solar cell can include forming a first dopant region over a silicon substrate and an oxide region over the first dopant region. In an embodiment, the oxide region can protect the first dopant region from a first etching process. In an embodiment, a second dopant region can be formed over the silicon substrate, where a mask can be formed to protect a first portion of the second dopant region from the first etching process. In an embodiment, the first etching process can be performed to expose portions of the silicon substrate and/or a silicon region. A second etching process can be performed to form a trench region to separate a first and second doped region of the solar cell. A third etching process can be performed to remove contaminants from the solar cell and remove any remaining portions of the oxide region.
