Abstract
A photovoltaic device according to the present disclosure is provided with: a condensing optical system having chromatic aberration; a first photoelectric converter, which is arranged on an optical axis of the condensing optical system; and a second photoelectric converter, which is arranged on an outer peripheral side of the first photoelectric converter when viewed from an optical axis direction of the condensing optical system, and which has a bandgap lower than a bandgap of the first photoelectric converter, wherein the first photoelectric converter is arranged on an inner side of a rectangle that circumscribes a condensing region of absorbable longest-wavelength light determined based on the bandgap.
