Wavelength dependence and figures of merit of ultrafast third-order optical nonlinearity of a conjugated 3,3'-bipyridine derivative.

Applied optics

Chen Q, Sargent EH, Leclerc N, Attias AJ.
PMID: 14717304
Appl Opt. 2003 Dec 20;42(36):7235-41. doi: 10.1364/ao.42.007235.

The wavelength dependence and figures of merit of the third-order optical nonlinearity of a conjugated 3,3'-bipyridine derivative, a designed nondipolar structure of the donor-acceptor-acceptor-donor type, are reported. Z scans reveal positive nonlinear refractive-index changes for wavelengths longer than the...

Ultrasensitive solution-cast quantum dot photodetectors.

Nature

Konstantatos G, Howard I, Fischer A, Hoogland S, Clifford J, Klem E, Levina L, Sargent EH.
PMID: 16838017
Nature. 2006 Jul 13;442(7099):180-3. doi: 10.1038/nature04855.

Solution-processed electronic and optoelectronic devices offer low cost, large device area, physical flexibility and convenient materials integration compared to conventional epitaxially grown, lattice-matched, crystalline semiconductor devices. Although the electronic or optoelectronic performance of these solution-processed devices is typically inferior...

Dead zones in colloidal quantum dot photovoltaics: evidence and implications.

Optics express

Barkhouse DA, Kramer IJ, Wang X, Sargent EH.
PMID: 21165075
Opt Express. 2010 Sep 13;18:A451-7. doi: 10.1364/OE.18.00A451.

In order to fabricate photovoltaic (PV) cells incorporating light-trapping electrodes, flexible foil substrates, or more than one junction, illumination through the top-contact (i.e.: non-substrate) side of a photovoltaic device is desirable. We investigate the relative collection efficiency for illumination...

Indole and 3-chloroindole: The source of the disagreeable odor of Hygrophorus paupertinus.

Mycologia

Wood WF, Smith J, Wayman K, Largent DL.
PMID: 21148987
Mycologia. 2003 Sep-Oct;95(5):807-8.

The odor emanating from sporocarps of Hygrophorus paupertinus is disagreeable and fecal-like. Solid phase microextraction (SPME) and analysis by gas chromatography-mass spectrometry (GC-MS) showed 1-octen-3-ol, indole and 3-chloroindole were responsible for the odor. This is the first case in...

Folded-light-path colloidal quantum dot solar cells.

Scientific reports

Koleilat GI, Kramer IJ, Wong CT, Thon SM, Labelle AJ, Hoogland S, Sargent EH.
PMID: 23835564
Sci Rep. 2013;3:2166. doi: 10.1038/srep02166.

Colloidal quantum dot photovoltaics combine low-cost solution processing with quantum size-effect tuning to match absorption to the solar spectrum. Rapid advances have led to certified solar power conversion efficiencies of over 7%. Nevertheless, these devices remain held back by...

Charge-extraction strategies for colloidal quantum dot photovoltaics.

Nature materials

Lan X, Masala S, Sargent EH.
PMID: 24553652
Nat Mater. 2014 Mar;13(3):233-40. doi: 10.1038/nmat3816.

The solar-power conversion efficiencies of colloidal quantum dot solar cells have advanced from sub-1% reported in 2005 to a record value of 8.5% in 2013. Much focus has deservedly been placed on densifying, passivating and crosslinking the colloidal quantum...

Measuring charge carrier diffusion in coupled colloidal quantum dot solids.

ACS nano

Zhitomirsky D, Voznyy O, Hoogland S, Sargent EH.
PMID: 23701285
ACS Nano. 2013 Jun 25;7(6):5282-90. doi: 10.1021/nn402197a. Epub 2013 May 31.

Colloidal quantum dots (CQDs) are attractive materials for inexpensive, room-temperature-, and solution-processed optoelectronic devices. A high carrier diffusion length is desirable for many CQD device applications. In this work we develop two new experimental methods to investigate charge carrier...

25th anniversary article: Colloidal quantum dot materials and devices: a quarter-century of advances.

Advanced materials (Deerfield Beach, Fla.)

Kim JY, Voznyy O, Zhitomirsky D, Sargent EH.
PMID: 24002864
Adv Mater. 2013 Sep 25;25(36):4986-5010. doi: 10.1002/adma.201301947. Epub 2013 Sep 04.

Colloidal quantum dot (CQD) optoelectronics offers a compelling combination of low-cost, large-area solution processing, and spectral tunability through the quantum size effect. Since early reports of size-tunable light emission from solution-synthesized CQDs over 25 years ago, tremendous progress has...

Self-assembled, nanowire network electrodes for depleted bulk heterojunction solar cells.

Advanced materials (Deerfield Beach, Fla.)

PMID: 23293006
Adv Mater. 2013 Mar 25;25(12):1769-73. doi: 10.1002/adma.201203759. Epub 2013 Jan 06.

Herein, a solution-processed, bottom-up-fabricated, nanowire network electrode is developed. This electrode features a ZnO template which is converted into locally connected, infiltratable, TiO2 nanowires. This new electrode is used to build a depleted bulk heterojunction solar cell employing hybrid-passivated...
