Concentrating solar panel

A photovoltaic device is disclosed comprising a concentrator and a collector. The concentrator is to concentrate solar energy, and the collector is positioned to receive solar energy from the concentrator. The concentrator comprises a plurality of identical flat linear fresnel prism sheets and the collector comprises a plurality of identical photovoltaic cells. The prism sheets are selected from the group consisting of square prism sheets and regular hexagonal prism sheets, and the cells, in a preferred embodiment, are selected from the group consisting of square cells where the prism sheets comprise square prism sheets and regular hexagonal cells where the prism sheets comprise hexagonal prism sheets. Each of the cells is sized substantially the same as the prism sheets and receives superposed beams of light from the prism sheets, each cell receiving superposed beams of light from four prism sheets where prism sheets are square, and superposed beams of light from six prism sheets where the prism sheets are hexagonal.
