Abstract:
A solar cell, comprising a solar collector with a transparent, rear-ventilated cover, a honeycomb structure with hollow spaces and walls which absorbs solar radiant heat located behind the cover, at least one heat insulation located behind the honeycomb structure, and at least one additional storage element for delayed release of absorbed heat into the inside of a building with which the solar cell is employed, characterized in that means are provided for permitting solar radiation at a chosen incident angle to enter the honeycomb structure and for compensating for sun-height induced incidence of radiant heat upon the honeycomb structure, the honeycomb structure, the heat insulation, and the storage element are permeable to vapor and are dimensioned such that vapor diffusion in both day and night phases is below a dew formation level, and in that the release of the heat taken up by the storage element takes place into an inside of the building with a delay from the take up time having a release maxima of at least 4 hours.
