PROBLEM TO BE SOLVED: To provide a concentrator photovoltaic module in which a ratio of an area of a light-receiving surface in an entire power generation member can be increased.SOLUTION: The concentrator photovoltaic module comprises a power generation member 3, a light collecting member and a light guide member. The power generation member includes: a photovoltaic element 32 which has a surface formed with a basic figure R selected from between rectangle or circle as a contour, uses a part of the surface as a light-receiving surface 30 on which sunlight is incident to perform photovoltaic power generation and uses the remaining surface as a notch 31 where photovoltaic power generation is not performed; and a contact part 33 which is provided on a surface of the notch 31 and to which wiring for extracting a current obtained by photovoltaic power generation on the light-receiving surface 30 is connected. The light collecting member collects incident sunlight. The light guide member has an emission surface formed in the same shape as or in a shape similar to the light-receiving surface 30, emits sunlight that is collected by the light collecting member and incident on an incidence plane, from an emission plane while improving uniformity of spatial distribution, and guides the sunlight to the light-receiving surface 30 of the power generation member 3.SELECTED DRAWING: Figure 2 |
