The invention relates to the 
photovoltaic power generation technology, and aims at providing a compact 
double reflection-type photovoltaic condenser based on compound eyes. The compact 
double reflection-type photovoltaic condenser based on the compound eyes comprises a photovoltaic 
cell and an optical collector, wherein the upper surface of the optical collector comprises a free curved surface and a 
refraction curved surface, the lower surface of the optical collector comprises a transmission plane and a reflection plane, the center of the 
refraction curved surface and the center of the reflection plane are positioned at the same vertical position, the center of the free curved surface and the center of the transmission plane are positioned at the same vertical position, and the free curved surface is arranged at a 
focal position of the 
refraction curved surface; and the photovoltaic 
cell is arranged outside the optical collector and adjoins to the transmission plane, the photovoltaic 
cell is positioned at a 
focal position of the free curved surface, and the aperture of the transmission plane is larger than that of the photovoltaic cell. The compact 
double reflection-type photovoltaic condenser has the advantages that the 
photovoltaic conversion efficiency of the photovoltaic cell is improved, the service life of the photovoltaic cell is prolonged, an optical plastic PMMA (
polymethyl methacrylate) is adopted and is prone to injection molding and 
processing, light in weight and applicable to large-scale 
processing, and the 
processing cost is reduced.
