The invention relates to a concentrator photovoltaic device (10) having a plurality of photovoltaic units (22) for directly converting solar energy into electrical energy, wherein a plurality of the photovoltaic units (22) are each provided with: a light entry surface (20) formed on a first optical unit (24), a solar cell (56) which has a smaller surface expanse than the light entry surface (20) of the photovoltaic device (22), the first optical unit (24) being designed to concentrate or focus the solar radiation entering through the light entry surface (20) onto a predetermined area (34) which is determined by the smaller surface of the solar cell (56), is at a spacing from the light entry surface (20) and is smaller in area than the light entry surface (20). In order to achieve a cheaper device by the use of smaller-area solar cells, without any problems in positioning them, it is proposed according to the invention that the plurality of photovoltaic units (22) are each provided with a retaining device (30) with which the associated solar cell (56) is positioned in the predetermined area (34), in that the retaining device (30) is attached by a first end (32) to the first optical unit (24) and that the solar cell (56) is attached to an opposing second end (34) of the retaining device (30). Moreover, a photovoltaic unit for such a device and an advantageous method for producing it are described.
