摘要: A device and method for fabrication of a multi-junction photovoltaic device includes providing a parent substrate including a single crystal III-V material. The parent substrate forms a III-V cell of the multi-junction photovoltaic device. A lattice-matched Germanium layer is epitaxially grown on the III-V material to form a final cell of the multi-junction photovoltaic device. The Germanium layer is bonded to a foreign substrate.
