A coated transparent substrate has a metallic or nitrided niobium, tantalum and/or zirconium functional layer and an aluminum and/or silicon nitride and/or oxynitride cover layer. A transparent substrate has a solar radiation active thin film stack comprising a functional layer based on metallic or partially or fully nitrided niobium, tantalum and/or zirconium covered by a layer based on aluminum nitride, aluminum oxynitride, silicon nitride and/or silicon oxynitride. Independent claims are also included for the following: (i) single or double glazing incorporating the above substrate; and (ii) a curtain wall-type facade face panel incorporating the above substrate with an opaque coating. Preferred Features: The substrate consists of clear or tinted glass or a flexible or rigid transparent polymer. L'invention a pour objet un substrat transparent muni d'un empilement de couches minces agissant sur le rayonnement solaire. L'empilement comprend une couche fonctionnelle en molybdène, et une surcouche en nitrure ou oxynitrure d'aluminium et/ou en nitrure ou oxynitrure de silicium.
