Abstract :
High-efficiency multifunction solar cells are attracting a great deal of attention for both space and terrestrial applications. We proposed the monolithic integration of the II/VI (ZnCdMg)(SeTe) and the III/V (InAlGa)(AsSb) material systems for multijunction solar cells. These material systems have direct bandgap, zinc blende, quaternary alloys, lattice-matched to GaSb substrates that cover the entire optical spectrum from greater than 3.0 eV to less than 0.4 eV; enabling the fabrication of high quality multijunction solar cells (with an arbitrary number of junctions) that are well matched to the solar spectrum.
