NOVELTY - The electronic device (4) has tin-plated copper conductors (6) that have high conductivity and section, and that are placed in a reliable and safe manner on an elongated plate of epoxy resin with glass fiber (5). Three Schottky type by-pass diodes (8) are assembled onto the elongated plate, and connected to the cables conducting the electricity generated by the photovoltaic module. The front face of the module is covered with an opaque white primer of a non-conductive material without ionic contamination and resistant to ultraviolet radiation.    USE - Elongated electronic device for embedding in photovoltaic module.    ADVANTAGE - Provides an elongated electronic device that has improved durability, rapid response, improved electrical protection and easy repair when compared with other already existing devices. Ensures that the front face of the electronic device is covered with a non-conductive white opaque primer material, without ionic contamination and resistant to ultraviolet radiation in order to reduce the circuit made on the rear side. Includes an encapsulation whose flexible nature prevents damage to the electrical and electronic components from impacts, vibration or fatigue, and which has the nature of good thermal conductivity thus helping with the dissipation of heat generated on the inside of the cable connection box. Ensures that encapsulation is also resistant to ultraviolet radiation and flames. Ensures a good mechanical and electrical connection and reduced losses of potential to a minimum from series resistance since electrical connection systems are used for the stated cables by means of mechanical crimping and soldering techniques.    DETAILED DESCRIPTION - The electronic device is embedded between the layers of encapsulating material, photovoltaic matrix (13), glass superstrate and rear insulating sheet inside of the photovoltaic module. Each by-pass diode protects a group of two rows of cells connected to each other in series and connected anti-parallel between them.    DESCRIPTION OF DRAWING(S) - The drawing shows the expanded perspective view of the rear face of a part of the assembly of a photovoltaic module, and illustrating the inside of the connection box so as to be able to clearly see the arrangement of the electronic device with by-pass diodes in the photovoltaic module.
