✦ Synopsis

An efficient Fresnel lens particularly designed for use with photovoltaic solar cells is described. The lens accomplishes different objectives: the whole energy band corresponding to the spectral response of the cell is focused on the cell; superposition of the spectra from various prisms yields a nearly uniform distribution of energy per unit area and unit time on the focal plane; the fraction of IR in the range where the cell has no response does not fall on the cell. The predicted performance of a methacrylate lens, assuming an air mass one spectral density, provides greater reliability.
