Resumen
The invention relates to a photovoltaic concentration module with an optical stage that operates by means of metallic reflection. The inside of the module is filled with a transparent optical liquid which provides continuous refractive index from the module inlet, formed by planar or curved transparent glass or plastic, to the actual cell. The cells are submerged in the liquid which cools same by means of natural or forced convection and fills all of the interior so as to prevent the passage of moisture and the formation of condensation inside the module.
