The project focused on fabrication of InP/Si laminate substrates as templates for growth of InGaAsP/InGaAs and InAlAs/InGaAsP/InGaAs multijunction solar cells. InP/Si template substrates were developed and used as templates for InGaAs solar growth. A novel feature of the program was development of the virtual substrate template, which enables a substrate to be formed with a lattice constant intermediate between those of GaAs and InP. Large-area virtual substrate templates were formed by transfer and bonding of dislocation free InGaAs films wafer onto silicon substrates.
