Title: Metamorphic two-junction photovoltaic devices with removable graded buffers

Abstract

The present disclosure relates to a method for manufacturing a device, where the device includes, in order, a metamorphic contact layer, a first metamorphic junction, a metamorphic tunnel junction, and a second metamorphic junction. To produce the device, the manufacturing includes, in order, a first depositing of a buffer layer onto a substrate, a second depositing of the metamorphic contact layer, a third depositing of the first metamorphic junction, a fourth depositing of the metamorphic tunnel junction, a fifth depositing of the second metamorphic junction, and the removing of the buffer layer and the substrate.
