Abstract
A method for the production of a photovoltaic device, for instance a solar cell, is disclosed. In one aspect, the method comprises providing a substrate having a front main surface and a rear surface. The method further comprises depositing a dielectric layer on the rear surface, wherein the dielectric layer has a thickness larger than about 100 nm. The method further comprises depositing a passivation layer comprising hydrogenated SiN on top of the dielectric layer and forming back contacts through the dielectric layer and the passivation layer. In another aspect, corresponding photovoltaic devices, for instance solar cell devices, are also disclosed.
