Abstract :
A hybrid solar system with high temperature stage is described. The system contains a radiation concentrator, a photovoltaic
solar cell and a heat engine or thermoelectric generator. Two options are discussed, one with a special PV cell
construction, which uses the heat energy from the part of solar spectrum not absorbed in the semiconductor material of
the cell; the other with concentration of the whole solar radiation on the PV cell working at high temperature and coupled
to the high temperature stage. The possibilities of using semiconductor materials with different band gap values are
analyzed, as well as of the different thermoelectric materials. The calculations made show that the proposed hybrid system
could be practical and efficient.
