摘要： A concentrator photovoltaic device includes: an optical concentrator; a solar battery cell; a homogenizer; a sealant; and a light transmission preventing layer. The homogenizer has a trapezoidal shape in which a sectional area at the optical concentrator side is larger than a sectional area at the solar battery cell side, a relationship of n h > n f > n t is satisfied among a refractive index n h of the homogenizer, a refractive index n f of the sealant, and a refractive index n t of the light transmission preventing layer, a thickness (H) of the light transmission preventing layer is equal to or larger than 0.1 mm and equal to or smaller than 1.2 mm, and a relationship of 0.5 ≤ b/a
