Inverted Metamorphic Multijunction Technology
National Renewable Energy Laboratory, Colorado, United States
Through an entirely new method of growing cells in an inverted sequence with a compositionally graded transition layer, NREL’s scientists are able to use high-quality “lattice-mismatched” materials to achieve high-performance crystal structures with optimal bandgaps. ranges.
Primary Application Area: Aerospace & Defense
Technology Development Status: Prototype
Technology Readiness Level: TRL 5

Value Proposition: 1 mounting a supporting carrier or “handle” to the cell allows it to be engineered optimally for a given application. 2) selectively removing the parent substrate – the material the cell is grown upon – creates an ultra-light, ultra-thin device with great flexibility, increasing the cell’s power-to-weight ratio tenfold.
