    Abstract: The embodiments relate to a method for producing a solar cell having a rear-side contact with a tunnel barrier. A monocrystalline wafer having a front side and a rear side may be provided with silicon and a dopant. A tunnel barrier is produced on the wafer, and a polycrystalline or amorphous layer is deposited on the tunnel barrier. The polycrystalline or amorphous layer includes silicon and a dopant. The polycrystalline or amorphous layer is removed on the front side by gas-phase etching.
