Photovoltaic panel (or solar panel) comprising: at least one luminescent solar concentrator (LSC) having an upper surface, a lower surface and one or more outer sides; at least one photovoltaic cell (or solar cell) placed on the outside of at least one of the outer sides or on the outside of at least one part of the lower surface of said luminescent solar concentrator (LSC); at least one rigid or semi-rigid support placed on the outside of said at least one photovoltaic cell (or solar cell), said at least one rigid or semi-rigid support being placed in direct contact with said at least one photovoltaic cell (or solar cell); at least one transparent frame placed outside said at least one rigid or semi-rigid support, said at least one transparent frame being placed in direct contact with said at least one rigid or semi-rigid support; optionally, at least one transparent protective shell placed between said at least one transparent frame and said at least one rigid or semi-rigid support, said at least one transparent protective shell being placed in direct contact with said at least one rigid or semi-rigid support and said at least one transparent frame. Said photovoltaic panel (or solar panel) may be used advantageously in various applications that require the production of electrical energy by utilizing the energy of solar radiation or radiation derived from artificial light such as, for example: architecturally integrated photovoltaic systems (“Building Integrated Photo Voltaic”—BIPV); photovoltaic windows; greenhouses; photo-bioreactors; soundproofing barriers; lighting engineering; design; advertising; automotive industry. Moreover, said photovoltaic panel (or solar panel) may be used either in “stand alone” conditions, or in modular systems.
