Abstract (en)

[origin: WO2021089528A1] The present invention relates to a multilayer stack used to form a photovoltaic device, the stack comprising at least: - an N-type conducting layer; - a P-type conducting layer; and - an active perovskite-type layer interposed between the N-type and P-type conducting layers, wherein the N-type conducting layer is made from individual nanoparticles of N-type metal oxide(s) and has a carbon content of less than or equal to 20 atomic%. The invention also relates to a method for preparing such a multilayer stack.
