ABSTRACT:
A photovoltaic cell formed on a crystal substrate in which the lattice constant of the material of which the substrate is composed differs from the lattice constant of crystal material of which at least one component cell is composed. A lattice-graded bridging epilayer is formed over curved surface regions of the crystal substrate.
