NOVELTY - The photovoltaic module (1) has support structure or casing (2), main optical concentrator (3), secondary optical component (4), and high-capacity photovoltaic cell (5). The support structure has variable configuration, and is made of plastics. The secondary optical component is made of reflecting material. An aluminum heat dissipator (7) with fins or rods (7a) and high dissipation coefficient is set beneath photovoltaic cell and in contact with adherent substance (6) that is a good conductor of heat. A protective component (8), made of thin, reflecting, heat-conducting film, is also provided.    USE - High-concentration photovoltaic module used in high-performance solar energy installations. Can be used for installation on building roofs, industrial factories and other locations.    ADVANTAGE - Provides an improved alternative in effectively acquiring high concentration of solar rays to be applied in high-performance solar energy installations, while ensuring reduced cost and improved yield. Uses lightweight support structures made of economical plastic materials, and ensures high levels of heat dissipation without increasing the size of the photovoltaic module. Uses Fresnel lens for greater degree of solar concentration. Ensures that the photovoltaic module has reduced fabrication costs and reduced weight due to its simple but effective modular structure. Ensures reduced transportation cost, simplified manufacture and simplified installation of the photovoltaic module. Allows easy incorporation of cooling circuit which uses cooling fluid to cool the photovoltaic module.    DETAILED DESCRIPTION - The heat dissipator takes as reference the ratio expressed as Rd-a is equal the value Td minus Ta over P, where R is the dissipation coefficient of the heat dissipator and is close to 3 (300 degrees/100 Watts) with a volume of 10 by 10 4 centimeters, Td is the temperature of the heat dissipator, Ta is the environmental temperature, and P is the energy dissipated per unit of time. The heat dissipator has a fin ratio in excess of 1 is to 5, in which the fin ratio is the width of space between the fins divided by the height.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic illustration showing the photovoltaic module incorporating a cooling system that uses the cooling fluid absorbed in a heat dissipator.
