PROBLEM TO BE SOLVED: To provide a concentrator photovoltaic power generation device in which increase in generated power is achieved by preventing reduction in efficiency during power generation.SOLUTION: A concentrator photovoltaic power generation device includes a lens substrate 3 where a plurality of lenses 31 are formed in a plane, and a power generation substrate 4 where a plurality of power generation cells 51, corresponding to the lenses 31, are formed in a plane. They are assembled while deviating the optical axis L1 of each lens 31 and the optical axis L2 of each power generation cell 51, previously in a direction for cancelling the deviation of the optical axes L1, L2 of the lens 31 and a corresponding power generation cell 51 due to difference in the expansion amount in the plane direction of the lens substrate 3 and power generation substrate 4 caused by temperature change from the assembly time. On the front surface of the power generation cell 51, a homogenizer 52 is provided while aligning the optical axes thus constituting a receiver 5.SELECTED DRAWING: Figure 3 |
