NOVELTY - The solar receiver (104) has multiple solar cells that are arranged in a string having a string axis and supported by a surface of a base plate. Each solar cell having a cell face receives solar radiation facing away from the base plate. Multiple fins made from single continuous sheet of metal and arranged in serpentine configuration, are attached directly to other surface of base plate and are extended outwardly from other surface in a direction perpendicular to both string axis and solar cell faces.    USE - Solar receiver of solar photovoltaic (PV) system. Can also be used in hybrid PV and thermal systems, biocollection system, and chemical and biological systems.    ADVANTAGE - The heat sink allows heat generated in the solar cells to dissipate upwardly by natural free convection through the multiple fins without obstruction or interference from the solar cell string, thus minimizes the temperature rise experienced by solar cells improving efficiency and prevents warping, electrical shorts, or any other malfunction due to high temperatures. The base plate has low mass such that it allows for a reduced lamination cycle time. As the heat sink has multiple interconnected fins forming a continuous roll of material to form a serpentine configuration, eliminates the need to assemble a heat sink using individual fins, hence can be easily manufactured with reduced cost. Reduces the weight and cost of the solar receiver by using a base plate that is made of flexible foil between the cell string and fins. The solar receiver is positioned such that the cell string is situated in front of the optical focus of the reflector panels, thus avoids extreme concentration areas of sunlight on cells which cause damage to cell and deleteriously affect its performance and avoids bringing the sunlight to a focus in front on the solar receiver which poses a safety hazard.
