Journal ArticleDOI
PbTe Colloidal Nanocrystals: Synthesis, Characterization, and Multiple Exciton Generation
James E. Murphy,Matthew C. Beard,Andrew G. Norman,S. Phillip Ahrenkiel,Justin C. Johnson,Pingrong Yu,Olga I. Micic,Randy J. Ellingson,Arthur J. Nozik +8 more
TL;DR: The first known observation of efficient multiple exciton generation (MEG) from single photons absorbed in PbTe NCs is reported, and calculated longitudinal and transverse Bohr radii for PbS, PbSe, and Pb Te NCs are reported to account for electronic band anisotropy.
Journal ArticleDOI
40.8% efficient inverted triple-junction solar cell with two independently metamorphic junctions
J. F. Geisz,Daniel J. Friedman,J.S. Ward,Anna Duda,Waldo J. Olavarria,Tom Moriarty,J. Kiehl,Manuel J. Romero,Andrew G. Norman,Kim M. Jones +9 more
TL;DR: In this paper, a photovoltaic conversion efficiency of 40.8% at 326 suns concentration is demonstrated in a monolithically grown, triple-junction III-V solar cell structure in which each active junction is composed of an alloy with a different lattice constant chosen to maximize the theoretical efficiency.
Journal ArticleDOI
Nanocrystalline TiO2 solar cells sensitized with InAs quantum dots.
TL;DR: N nanocrystalline TiO2 solar cells sensitized with InAs quantum dots, which are stable for at least weeks under room light in air and power conversion efficiency of about 1.7% under 5 mW/cm2 is reported.
Journal ArticleDOI
Six-junction III–V solar cells with 47.1% conversion efficiency under 143 Suns concentration
J. F. Geisz,Kevin L. Schulte,Myles A. Steiner,Andrew G. Norman,Harvey Guthrey,Matthew Young,Tao Song,Thomas Moriarty +7 more
TL;DR: Geisz et al. as discussed by the authors presented a series-connected, six-junction inverted metamorphic structure with a 1-Sun global efficiency of 39.2% when tuned to the global spectrum.
Journal ArticleDOI
An artificial interphase enables reversible magnesium chemistry in carbonate electrolytes.
Seoung-Bum Son,Tao Gao,Steve Harvey,K. Xerxes Steirer,Adam A. Stokes,Adam A. Stokes,Andrew G. Norman,Chunsheng Wang,Arthur v. Cresce,Kang Xu,Chunmei Ban +10 more
TL;DR: By engineering an artificial Mg2+-conductive artificial interphase on the Mg anode surface, which successfully decouples the anodic and cathodic requirements for electrolytes and demonstrate highly reversible Mg chemistry in oxidation-resistant electrolytes, a new avenue is provided not only for Mg but also for other multivalent-cation batteries facing the same problems.
