Method for manufacturing a solar cell with a surface-passivating dielectric double layer, and corresponding solar cell

We will describe a solar cell with a Dielektrikumdoppelschicht and a method for their preparation. It comprises a first dielectric layer (3) containing aluminum oxide or consisting of alumina, and a second, hydrogen-containing dielectric layer (5) is produced by sequential vapor deposition, whereby a very good passivation of the surface of solar cells can be achieved
