Method for manufacturing a photovoltaic module (1) comprising: a) providing an electrically conductive substrate, the substrate being provided with a predetermined electrical pattern; b) depositing a solder paste (7) onto the electrically conductive substrate at pre-defined interconnection locations; c) placing a first encapsulant layer (3) provided with a pattern of openings onto the electrically conductive substrate, the pattern of openings corresponding with the locations of the solder paste (7); d) placing back-contact solar cells (4) on the first encapsulant layer so as to have a match of the electrical pattern of the back-contact solar cells with the electrical pattern of the electrically conductive substrate; e) placing a second encapsulant layer (5) on the back-contact solar cells (4), and placing a glass layer (6) on the second encapsulant layer (5); ; f) applying heat and pressure to the components (2, 3, 4, 5, 6, 7) to cause the encapsulant materials to flow and form a monolithic photovoltaic modul
