Photovoltaic cell comprising, an assembly comprising a substrate, first and second passivation layers covering opposite faces of the substrate and also lateral faces of the substrate, and first and second charge-collecting layers; a first layer of TCO disposed against the first main face of the assembly and such that edges of the first main face of the assembly are not covered by the first layer of TCO; a second layer of TCO covering the whole of the second main face of the assembly; a non-reflective coating partly covering the first and/or second charge-collecting layers on the lateral faces of the substrate and not covered by the second layer of TCO, and also covering the edges of the first main face.
