1. Method for manufacturing a silicon solar cell, including the following steps:

  • providing a silicon substrate;

    depositing a first dielectric layer having a thickness of less than 50 nm on a surface of the silicon substrate by means of atomic layer deposition, wherein the first dielectric layer comprises aluminium oxide; and

    depositing a second dielectric layer directly on a surface of the first dielectric layer, materials of the first dielectric layer and the second dielectric layer differing and hydrogen being embedded into the second dielectric layer.
