PHOTOVOLTAIC MODULE Russian patent published in 2010 - IPC F24J2/08 

FIELD: physics; optics.

SUBSTANCE: invention relates to solar power engineering, particularly to concentrating photovoltaic modules for generating electricity. The photovoltaic module has sidewalls, a top panel made from silicate glass, plane-convex lenses attached to the outer surface of a lower panel and coaxial with corresponding Fresnel lenses, as well as heat-removing conduits hermetically joined to the outer surface of the lower panel, where the said heat-removing conduits have a flat bottom with photocells on the inner surface of the said bottom, with optical axes of corresponding Fresnel lenses passing through the central longitudinal line of the said photocells. Distance between the lower panel and the flat surface of the bottom of the heat-removing conduits is greater than total thickness of the photocells and the plane-convex lens, but is not greater than their focal distance. There are ventilation holes in the sidewalls directly under the top and over the bottom surfaces of corresponding panels. The module has plane-convex lenses and heat-removing conduits similar to the first attached to the outer surface of one sidewall, with solar cells on the inner surface of the bottom of the heat-removing conduits, and infrared photocells fitted on the inner surface of the bottom of the first heat-removing conduits, as well as an intermediate panel with a spectrum-dividing coating, fitted at an angle to the optical axis of the module, providing for optical connection of the said coating with the first and second plane-convex lenses. On the inner surface of the bottom of all heat-removing conduits, thermoelectric converters are brought into contact with air coolers.

EFFECT: increased efficiency of converting solar radiation to electrical energy with longer service life of the device.
