NOVELTY - The module (101) has a photovoltaic cell assembly (102) in which several photovoltaic cells (120) whose surface side becomes light receiving element (119) and located in parallel at rectangular shape. A cooling structure (103) comprises integral casting that covers whole back surface of photovoltaic cell assembly, and a channel for coolant duct (123). Several condensing casings (104) are provided in the surface side of the photovoltaic cell assembly, and the light receiving element of each photovoltaic cell are made to concentrate light.    USE - Solar power generation module used in concentrating type solar energy power generation system (claimed).    ADVANTAGE - The heat produced at the time of light reception can be cooled, as cooling structure is provided to cover the whole back surface of the photovoltaic cell assembly that is located in parallel at rectangular shape, the photovoltaic cell can be efficiently cooled, and coolant can respond to high thermal load, as the integral casting is provided with a channel for coolant, and the pressure loss of coolant can be low, as the turn portion of the channel for coolant is reduced. The effect of cooling capacity cannot be declined easily, and can respond to the high temperature by the condensing degree, and the light which the solar power generation module light-received can be unwastefully utilized for electric power generation, and electric power generation amount can be increased, as several condensing casing on which each light receiving element is made to concentrate light is provided.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for concentrating type solar energy power generation system.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the condensing state of solar power generation module.
