ABSTRACT
FULLSPECTRUM is an EU integrated project whose primary objective is to make use of the FULL
solar SPECTRUM to produce electricity. The necessity for this research is easily understood, for example,
from the fact that present commercial solar cells used for terrestrial applications are based on
single gap semiconductor solar cells. These cells can by no means make use of the energy of below
bandgap energy photons, since these simply cannot be absorbed by the material. The achievement
of this general objective is pursued through five strategies:
a) the development of high efficiency multijunction solar cells based on III-V compounds,
b) the development of thermophotovoltaic converters,
c) the research on intermediate band solar cells,
d) the search of molecules and dyes capable of undergoing two photon processes and
e) the development of manufacturing techniques suitable to industrialize the most promising
concepts.
