Abstract
Abstract A solar photoelectric conversion apparatus comprises a light converter immersed in a transparent liquid heat carrier which occupies the lower part of the cavity of a hollow hermetically sealed reservoir. The apparatus also includes a solar radiation concentrator inserted in a beam of a solar radiation incident on an active surface of the light converter. During operation of the apparatus, vapors of the heat carrier condense on the inner walls of the reservoir and return by gravity to the liquid in the lower portion of the cavity, thereby cooling the liquid and the light converter immersed therein by "thermal siphon" action.

Claim 1
Independent Claim
134 words
A solar photoelectric conversion apparatus comprising a hollow hermetically sealed reservoir; a transparent liquid heat carrier within said reservoir and occupying the lower portion of the cavity formed by the reservoir; a light converter immersed in said heat carrier and having an active surface; a solar concentrator adapted to be in the optical path of a beam of a solar radiation incident on said active surface of said light converter; and power leads of said light converter running out of said reservoir without disturbing its hermetic condition, whereby during operation of the apparatus vapors of the heat carrier condense on the inner walls of said reservoir and return by gravity to said liquid in said lower portion of said cavity, thereby cooling said liquid and said light converter immersed therein by "thermal siphon" action.
