Lattice Matched Multi- Junction Photovoltaic and Optoelectronic Devices

The present invention provides semiconductor structures comprising a substrate and at least three III-V and/or II- VI multi-junction building blocks, each comprising a p-n junction having at least two alloy layers, formed over the substrate, provided at least one multi-junction building block comprises II-VI alloy layers. Further described are methods for preparing semiconductor structures utilizing a sacrificial or etch-stop ternary III-V alloy layer over an III-V substrate.
