Embodiment Construction

[0033] figure 1 The Hybrid Solar Collector 2 is capable of converting solar energy into electricity and heat at the same time.

[0034] The collector 2 comprises at least one photovoltaic cell 4 for converting solar energy into electrical energy and at least one radiator 6 arranged to receive the solar energy transmitted through the photovoltaic cell 4 and convert the solar energy into thermal energy by heating a fluid.

[0035] Collector 2 is aggregated. It comprises means for concentrating the incident solar beam 8 into a concentrated solar beam 10 oriented towards the energy conversion means defined by the photovoltaic cells 4 and the heat sink 6 .

[0036] In the example shown, the concentrating means are assumed to be in the form of a cylindrical parabolic mirror 12 oriented to direct the concentrated light beam 10 towards the energy conversion means, preferably located substantially at the focal point of the mirror 12 .

[0037] In a known manner, the concentrator 2 ca...

Abstract

The invention relates to a collector including at least one photovoltaic cell for converting solar energy into electric energy, and at least one heat sink (6) for converting solar energy into heat energy by heating a fluid, arranged so as to receive solar energy through the photovoltaic cell (4). According to one form of the invention, the photovoltaic cell (4) includes a plurality of vertically adjacent semiconductor junctions having different forbidden energy bands, each semiconductor junction having a forbidden energy band of greater than or equal to 1.2 eV, in particular greater than or equal to 1.4 eV.

Description

technical field [0001] The invention relates to the field of hybrid solar energy converters. Background technique [0002] The name "hybrid" solar collector is because it converts the received solar energy into different forms of energy, especially electricity and heat. [0003] One type of hybrid solar collector that may be provided includes at least one photovoltaic cell for converting solar energy into electrical energy and at least one heat sink arranged to receive solar energy transmitted through the photovoltaic cell and heat a fluid Convert solar energy into heat energy. [0004] Solar energy, not converted to electricity by the photovoltaic cells, heats the fluid circulating in the pipes and is thus converted to thermal energy. [0005] In order to increase the output of converted / received solar energy of photovoltaic cells, it has been considered that photovoltaic cells employ multiple vertically adjacent semiconductor junctions with forbidden energy bands (or "ba...
