Hybrid solar energy collector and solar power plant comprising at least such a collector

摘要

A collector is provided including at least one photovoltaic cell for converting solar energy into electric energy, and at least one heat sink for converting solar energy into heat energy by heating a fluid, arranged so as to receive solar energy through the photovoltaic cell. The photovoltaic cell 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.
