A solar cell comprising a substrate, a buffer layer, a first subcell, a second subcell, and a third subcell, where said first subcell, said second subcell, and said third subcell are lattice matched, and where said substrate is lattice mismatched with said first, second, and third subcells.

Multi-junction photovoltaic cell

A ferroelectric device that comprises a polarizing thin film of BaMF.sub.4 deposited on a substrate. Ba is barium, M is one of the metals of the group consisting of iron (FE), manganese (Mn), cobolt (Co), nickel (Ni), magnesium (Mg), and zinc (Zn). The substrate is silicon, sapphire, or gallium arsenide. A non-volatile NDRO and DRO memory cell and methods for depositing the thin film. A method of depositing bismuth titanate on a substrate are described.
