NOVELTY - The high gain photovoltaic concentrato has a photovoltaic concentration module that works by optical reflection metal, where inner part of the module is filled with a liquid that provides transparent optical continuity of refractive index. The entry module has a flat or curved glass or transparent plastic. The cells are immersed in the liquid, which meets functions of cooled natural or forced convection.    USE - High gain photovoltaic concentrator for use with a reflective phase in an optical dielectric liquid.    DETAILED DESCRIPTION - High concentration photovoltaic module with a compact optical reflection metallic phase comprising: (a) a series of reflective optical elements (1) arranged in the ground formation and up the side of the module; (b) a substrate of glass or transparent plastic (4), flat or curved, which is comprises front side of the module, and whose lower side attached to the photovoltaic cells (2), and strips of conductive material (3) formed by cables or other connection elements; (c) profiles (6) located on the sides of the module sealed hermetically, and frameworks (7) attached to the profiles (6), and which contain elements of support to the subject of the module to a structure that follows sun; and (d) a transparent optical fluid (5) that fills the interior of the module, wrapping all reflective optical elements (1) and photovoltaic cells (2), whose functions are to carry heat to the front side, back, and sides of module, providing continuity of refractive index in the optical system from which the light enters through the front of the module until it reaches the cells and simultaneously preventing the entry of humidity and condensation of water vapor inside the module, is new.
