摘要
The invention relates to a bifacial solar cell having a rear layer stack, characterised in that the rear layer stack has an AlOx layer (1), one or more SiNx layers (2, 3, 5), and an SiOxNy layer (4). The invention also relates to a solar module which has multiple such bifacial solar cells. The invention furthermore relates to a method for producing the bifacial solar cell in which the rear layer stack consisting of the AlOx layer (1), SiNx layer(s) (2, 3, 5) and SiOxNy layer (4) is deposited in a tube-type PECVD system with a graphite boat as the wafer holder, and the layers are applied successively in the same tube.
