NOVELTY - The conductive and reflective sheet (1A) has metal contacts (1J) with high conductivity and reflectance. The metal contacts are electrically connectable to the photovoltaic cells (1B). The metal contacts contain aluminum or an alloy of metals conductors such as copper or platinum coated with evaporated aluminum.    USE - Conductive and reflective sheet for using concentrated solar radiation with the use of photovoltaic cells provided in the form of batteries.    ADVANTAGE - Provides a conductive and reflective sheet that optimizes the conversion of the radiation, particularly the concentrated solar power, by using photovoltaic cells while ensuring manufacturing cost of the conductive and reflective sheet. Reduces losses arising from the reflection of the radiation on the photovoltaic cell surface, because the radiation is confined to the inside of the concentrated solar radiation device. Allows the progressive use of enclosures to vary the intensity of incident radiation. Ensures that the concentrated solar radiation device has compact and modular design through the distribution of photovoltaic cells for concentrated radiation inside the concentrated solar radiation device. Allows the use of photovoltaic cells without the need to manufacture them with electrical circuit label and printed size code, and ensures greater utilization of the surface of the photovoltaic cells because the photovoltaic cells are not covered. Allows the use of photovoltaic cells without the need of forming the photovoltaic cells with textured surface layers to prevent reflections on the surfaces of the photovoltaic cells. Allows the use of photovoltaic cells without antireflective coating layer. Allows the irradiation of photovoltaic cells on both sides with different levels of intensity on each side, with the consequent increased precision and intensity of radiation at a certain depth of the photovoltaic cell. Allows the cooling of the concentrated solar radiation device in an efficient and compact manner. Allows the use of photovoltaic cells in a vacuum environment. Reduces the length of the electrical circuits to allow the best use of the conversion of electrical energy.
