Journal ArticleDOI
Quantum dot solar cells
TL;DR: In this article, three QD solar cell configurations are described: (1) photoelectrodes comprising QD arrays, (2) QD-sensitized nanocrystalline TiO 2, and (3) QDs dispersed in a blend of electron- and hole-conducting polymers.
Journal ArticleDOI
Highly Efficient Multiple Exciton Generation in Colloidal PbSe and PbS Quantum Dots
Randy J. Ellingson,Matthew C. Beard,Justin C. Johnson,Pingrong Yu,Olga I. Micic,Arthur J. Nozik,Andrew Shabaev,Alexander L. Efros +7 more
TL;DR: It is found that the biexciton effect, which shifts the transition energy for absorption of a second photon, influences the early time transient absorption data and may contribute to a modulation observed when probing near the lowest interband transition.
Journal ArticleDOI
Peak external photocurrent quantum efficiency exceeding 100% via MEG in a quantum dot solar cell.
Octavi E. Semonin,Octavi E. Semonin,Joseph M. Luther,Sukgeun Choi,Hsiang-Yu Chen,Jianbo Gao,Jianbo Gao,Arthur J. Nozik,Arthur J. Nozik,Matthew C. Beard +9 more
TL;DR: It is demonstrated that MEG charge carriers can be collected in suitably designed QD solar cells, providing ample incentive to better understand MEG within isolated and coupled QDs as a research path to enhancing the efficiency of solar light harvesting technologies.
Journal ArticleDOI
Comparing photosynthetic and photovoltaic efficiencies and recognizing the potential for improvement.
Robert E. Blankenship,David M. Tiede,James Barber,James Barber,Gary W. Brudvig,Graham R. Fleming,Graham R. Fleming,Maria L. Ghirardi,Marilyn R. Gunner,Wolfgang Junge,David Kramer,Anastasios Melis,Thomas A. Moore,Christopher C. Moser,Daniel G. Nocera,Arthur J. Nozik,Arthur J. Nozik,Donald R. Ort,William W. Parson,Roger C. Prince,Richard T. Sayre +20 more
TL;DR: Natural photosynthesis is compared with present technologies for photovoltaic-driven electrolysis of water to produce hydrogen and opportunities in which the frontiers of synthetic biology might be used to enhance natural photosynthesis for improved solar energy conversion efficiency are considered.
Journal ArticleDOI
Solar conversion efficiency of photovoltaic and photoelectrolysis cells with carrier multiplication absorbers
Mark C. Hanna,Arthur J. Nozik +1 more
TL;DR: In this article, the maximum power conversion efficiency for conversion of solar radiation to electrical power or to a flux of chemical free energy for the case of hydrogen production from water photoelectrolysis was calculated.
