Heat insulations in houses having card-board lattice arranged behind a glass pane yield, in practice, a heat flow which is dependent on insolation. Said heat flow is lower at night and during weak insolation and begins to increase when the lattice is solar heated. The inventive solar cell (1) comprises a lattice (5) which is situated behind a rear-ventilated glass pane (2) and which exhibits durable storage properties. The solar cells characterize a solar energy yield (v′) by an arrangement which selects for an angle of incidence. Said solar energy yield does not lead to overheating in the room interior (R) also when the sun is at a high position. A thermal time constant is obtained by means of heat insulations (11, 12, 13) which are connected in succession. Said time constant guarantees comfortable temperatures in the interior (R) of the house also in the case of low supplementary heating. The solar cell (1) considerably reduces heat requirements and can be optimally adapted to a wide range of local climate relationships.
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.
The solar cell according to claim, 1 or 11, characterized in that the honeycomb hollow spaces are at least partly provided with an additional heat insulation.
