James D. McCambridge,Myles A. Steiner,Blair L. Unger,Keith Emery,Eric L. Christensen,Mark Wanlass,Allen L. Gray,Laszlo A. Takacs,Roger F. Buelow,Timothy A. McCollum,James W. Ashmead,Greg Schmidt,Alex W. Haas,J. R. Wilcox,James Van Meter,J.L. Gray,Duncan T. Moore,Allen Barnett,Richard J. Schwartz +18 more
TL;DR: In this article, a small, integrated photovoltaic module was designed, fabricated, and tested, consisting of two separately-contacted, high efficiency, multijunction solar cells and non-imaging optics that both concentrate and spectrally split the incoming light.
Patent
Materials and processes for releasing printable compound semiconductor devices
Matthew Meitl,Christopher A. Bower,Etienne Menard,James F. Carter,Allen L. Gray,Salvatore Bonafede +5 more
TL;DR: In this paper, a method of fabricating transferable semiconductor devices includes providing a release layer including indium aluminum phosphide on a substrate, and providing a support layer on the release layer.
Patent
Off-Cut Substrates In Inverted Metamorphic Multijunction Solar Cells
TL;DR: In this paper, a multijunction solar cell including an upper subcell, a middle subcell and a lower subcell was constructed by providing a substrate having an offcut of 15° from the (001) plane to the (111) plane for the epitaxial growth of semiconductor material.
