Journal ArticleDOI
Trap-State Distributions and Carrier Transport in Pure and Mixed-Phase TiO2 : Influence of Contacting Solvent and Interphasial Electron Transfer
TL;DR: In this article, the room-temperature photoluminescence spectra of nanocrystalline TiO2 in the anatase and rutile phases and in mixed-phase samples obtained commercially (Degussa P25) and by thermal treatment of anatase were reported.
Journal ArticleDOI
Location Of Hole And Electron Traps On Nanocrystalline Anatase TiO2
Candy C. Mercado,Fritz J. Knorr,Jeanne L. McHale,Shirin M. Usmani,Andrew S. Ichimura,Laxmikant V. Saraf +5 more
TL;DR: The defect photoluminescence from TiO2 nanoparticles in the anatase phase is reported for nanosheets which expose predominantly (001) surfaces and compared to that from conventional anatase nanoparticles which expose mostly (101) surfaces as discussed by the authors.
Journal ArticleDOI
Controlled Humidity Study on the Formation of Higher Efficiency Formamidinium Lead Triiodide-Based Solar Cells
Sarah Wozny,Mengjin Yang,Alexandre M. Nardes,Candy C. Mercado,Suzanne Ferrere,Matthew O. Reese,Weilie Zhou,Kai Zhu +7 more
TL;DR: In this paper, the effect of humidity on the structural, optical, and electrical properties of planar FAPbI3 solar cells was investigated and it was shown that higher humidity leads to lower device performance, mainly due to the loss of open-circuit voltage and fill factor.
Journal ArticleDOI
Photoluminescence of dense nanocrystalline titanium dioxide thin films: effect of doping and thickness and relation to gas sensing.
TL;DR: The dependence of the optical absorption, Raman spectra, and PL spectra on heat treatment and dopants reveals the role of oxygen vacancies, crystallinity, and phase transformation in the performance of TiO(2) films used as gas sensors and the chemical nature of luminescent defects.
Journal ArticleDOI
Site-Selective Passivation of Defects in NiO Solar Photocathodes by Targeted Atomic Deposition
Cory J. Flynn,Shannon M. McCullough,EunBi Esther Oh,Lesheng Li,Candy C. Mercado,Byron H. Farnum,Wentao Li,Carrie L. Donley,Wei You,Arthur J. Nozik,Arthur J. Nozik,James R. McBride,Thomas J. Meyer,Yosuke Kanai,James F. Cahoon +14 more
TL;DR: The TAD process eliminates all measurable defects in NiO, leading to a nearly 3-fold improvement in the performance of dye-sensitized solar cells and could be implemented with a range of vapor-phase precursors and developed into a general strategy to passivate defects in zero-, one-, and two-dimensional nanomaterials.
