<p>A solar power station, in particular of a relatively small size, for generating both electricity and useful heat. Photovoltaic cells (34) are fitted to a hollow holder (33) bearing a flow of cooling fluid. That part of the light spectrum which can be converted into electricity by the photovoltaic cells only at a low efficiency or not at all is filtered out by tubular glass bodies (31, 32), so that the heat loading on the photovoltaic cells is reduced. In the annular space between the glass tubes (31), the cooling fluid preheated in the interior of the holder (33) circulates and is further heated here by its own heat absorption and the removal of the heat absorbed in the glass bodies (31, 32). This cooling fluid can be used for heating purposes. The glass bodies (31 and 32) can be made of glasses of different types, which absorb light in the lower or upper part of the spectrum respectively. <IMAGE></p> |
