Abstract: A solar photovoltaic battery having a diffractive holographic optical element comprised of a concentrator and a dispersive element contains photodetectors for all wavelengths, an input Fresnel lens or ordinary lens, and a set of lenses mounted on the main optical axis. The photoelements are concave, convex and in the form of flat plates and are mounted on the main optical axis beyond the point of entry of the sun's rays, downstream of the holographic concentrator. The flat photoelements are mounted at or close to the focus of the sun's rays; the concave photoelements are mounted behind the focus of the sun's rays; and the convex photoelements are mounted in front of the focus of the sun's rays.

A solar photovoltaic battery having a diffractive holographic optical element comprised of a concentrator and a dispersive element contains photodetectors for all wavelengths, a spherical mirror, and a set of lenses. The photoelements are concave, convex and in the form of flat plates and are mounted along the main optical axis, symmetrically on either side of the holographic concentrator. The flat photoelements are mounted at or close to the focus of the sun's rays; the concave photoelements are mounted behind the focus of the sun's rays; and the convex photoelements are mounted in front of the focus of the sun's rays. A solar photovoltaic battery having a diffractive holographic optical element comprised of a concentrator and a dispersive element contains photodetectors for all wavelengths, a housing, an input Fresnel lens and a spherical mirror having a diameter greater than the input lens, two sets of lenses mounted symmetrically on either side of the holographic concentrator, the latter being situated on the main optical axis of the input lens and the mirror, and a transparent cover. The photoelements are concave, convex and in the form of flat plates and are mounted along the main optical axis, symmetrically on either side of the holographic concentrator. The flat photoelements are mounted at or close to the focus of the sun's rays; the concave photoelements are mounted behind the focus of the sun's rays; and the convex photoelements are mounted in front of the focus of the sun's rays.
