NOVELTY - The method involves applying photovoltaic cells (7) under the form of films on a surface (2a) of an armature (2) provided with an anti-exudation layer. A bituminous mass is applied on another surface of the armature. The photovoltaic cells are glued on the armature, and an adhesive layer is applied on the armature before applying the photovoltaic cells. The photovoltaic cells are covered with another adhesive layer and a protection layer. An ethylene vinyl acetate film (4) is used for two adhesive layers, and a PTFE film (13) is used for the protection layer.    USE - Method for manufacturing a bituminous membrane (claimed) that is applied on a roof of a building and used as an energy source by capturing solar energy using photovoltaic cells.    ADVANTAGE - The photovoltaic cells are glued on the armature, thus ensuring mechanical and rapid application of the photovoltaic cells on the armature. The adhesive layer is applied on the armature before applying the photovoltaic cells, and the cells are covered with the other adhesive layer and the protection layer, so that the photovoltaic cells are sandwiched between the two adhesive layers and the protection layer, thus ensuring better adherence of the photovoltaic cells on the armature, and protection of the photovoltaic cells. The ethylene vinyl acetate film is used for the two adhesive layers, so as to ensure better resistance to heat when the bituminous mass is applied. The method ensures better sealing and electrical efficiency of the membrane over time. The membrane having the photovoltaic cells is applied on the roof in an inexpensive manner. The anti-exudation layer limits migration of oil in the bituminous mass, thus avoiding the risk of easy detachment of the cells due to migration of oil.
