    Abstract: Multijunction solar cell structures (100) including high quality epitaxial layers of monocrystalline semiconductor materials that are grown overlying monocrystalline substrates (102) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers are disclosed. One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer (104) on a silicon wafer. The accommodating buffer (104) layer is a layer of monocrystalline material spaced apart from the silicon wafer by an amorphous interface layer (112) of silicon oxide. The amorphous interface layer (112) dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. Multiple and varied accommodating buffer layers can be used to achieve the monolithic integration of multiple non-lattice matched solar cell junctions.

    Abstract: High quality epitaxial layers of compound semiconductor materials (26) can be grown overlying large silicon wafers (22) by first growing an accommodating buffer layer (24) on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer (28) dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer.

    Abstract: High quality epitaxial layers of monocrystalline materials suitable for forming complimentary III-V field effect transistors (340) can be grown overlying monocrystalline substrates (350) such as large silicon wafers by forming a compliant substrate (346) for growing the monocrystalline layers and a buffer structure overlying the compliant substrate (346). One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer (354) on a silicon wafer (350). The accommodating buffer layer (354) is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide (352).
