Solar photoelectric module

Claim 2

A solar photoelectric module, comprising: a solar energy concentrator, said concentrator being made as a hermetically sealed hollow vessel having at least one transparent wall and formed in the shape of a convergent lens; a transparent heat transfer agent filling said vessel; a photovoltaic solar energy converter accommodated inside said vessel in said heat transfer agent and having at least one effective surface; said photovoltaic solar energy converter being so oriented that solar radiation concentrated by said concentrator impinges upon said effective surface of said photovoltaic solar energy converter; current leadouts from said photovoltaic solar energy converter extending to the exterior of said vessel without impairing the hermetic sealing thereof; and a reflector located outside of said vessel opposite said effective surface of said photovoltaic solar energy converter.

Claim 3

A solar photoelectric module as claimed in claim 1, wherein said reflector located outside of said vessel opposite said effective surface of the photovoltaic solar energy converter is a specular reflector.

Claim 4

A solar photoelectric module as claimed in claim 2, wherein said specular reflector is made flat and is spaced apart from said effective surface of the photovoltaic solar energy converter at a distance nearly equal to half the focal length of said lens.

Claim 5

A solar photoelectric module as claimed in claim 3, wherein said photovoltaic solar energy converter is provided with two effective surfaces, further comprising an additional convergent lens arranged opposite said other effective surface of the photovoltaic solar energy converter at a distance approximately equal to the focal length of said lens, the area of said additional lens being about half the area of said principal lens.

Claim 6

A solar photoelectric module as claimed in claim 2, wherein said photovoltaic solar energy converter is located in the bottom portion of said lens; and said specular reflector makes angle with the optical axis of said lens so as to reflect solar radiation onto said effective surface of the photovoltaic solar energy converter.

Claim 7

A solar photoelectric module as claimed in claim 2, wherein said photovoltaic solar energy converter is provided with two effective surfaces and an additional specular-type solar radiation reflector which is situated opposite said other effective surface of the photovoltaic solar energy converter at a distance sufficient to provide reflection of solar radiation by said additional reflector onto said other effective surface of the photovoltaic solar energy converter; said principal specular reflector being made of two components, a central portion adapted for reflecting solar radiation onto said first effective surface of the photovoltaic solar energy converter, and a peripheral portion adapted for reflecting solar radiation onto said additional reflector.

Claim 8

A solar photoelectric module, comprising: a first hollow, hermetically sealed, transparent convergent lens; a second transparent convergent lens similar to the aforesaid one and spaced apart therefrom at a distance nearly equal to the focal length of the abovementioned lenses, each of said lenses being filled with a heat transfer agent; first and second photovoltaic solar energy converters, each having effective surface; one of said photovoltaic solar energy converters being situated at the center of each of said lenses with said effective surfaces facing each other; said first lens serving as the solar energy concentrator for said photovoltaic solar energy converter situated in said second lens; said second lens serving as the solar energy concentrator for said photovoltaic solar energy converter located in said first lens; first and second specular reflectors, each situated opposite each of said lenses at an angle to the optical axis of a given lens so as to direct solar radiation simultaneously onto said effective surfaces of both of said photovoltaic solar energy converters; current leadouts from said photovoltaic solar energy converters extending outside of said lenses without impairing the hermetic sealing thereof.
