Journal ArticleDOI
Nanoscale Phase Separation and High Photovoltaic Efficiency in Solution-Processed, Small-Molecule Bulk Heterojunction Solar Cells
Bright Walker,Arnold B. Tamayo,Xuan-Dung Dang,Peter Zalar,Jung Hwa Seo,Andres Garcia,Mananya Tantiwiwat,Thuc-Quyen Nguyen +7 more
TL;DR: In this article, a non-polymeric, diketopyrrolopyrrole-based donor material that can be solution processed with a fullerene acceptor to produce good quality films is reported.
Journal ArticleDOI
Mechanism of Phosphorescence Appropriate for the Long-Lasting Phosphors Eu2+-Doped SrAl2O4 with Codopants Dy3+ and B3+
F. Clabau,Xavier Rocquefelte,Stéphane Jobic,Philippe Deniard,Myung-Hwan Whangbo,Andres Garcia,T. Le Mercier +6 more
TL;DR: In this article, the authors formulated a new mechanism of phosphorescence on the basis of the fact that the d orbitals of Eu2+ are located near the conduction band bottom of SrAl2O4, and that the Eu 2+ concentration decreases during UV excitation.
Journal ArticleDOI
Recent Applications of Conjugated Polyelectrolytes in Optoelectronic Devices
TL;DR: In this paper, the basic properties of conjugated polyelectrolytes as a function of molecular structure and their use to improve charge injection from metallic electrodes into organic semiconductors, a key requirement in emissive devices, are discussed.
Journal ArticleDOI
Evidence for near-Surface NiOOH Species in Solution-Processed NiOx Selective Interlayer Materials: Impact on Energetics and the Performance of Polymer Bulk Heterojunction Photovoltaics
Erin L. Ratcliff,Jens Meyer,K. Xerxes Steirer,Andres Garcia,Joseph J. Berry,David S. Ginley,Dana C. Olson,Antoine Kahn,Neal R. Armstrong +8 more
TL;DR: In this paper, the characterization and implementation of solution-processed, wide bandgap nickel oxide (NiOx) hole-selective interlayer materials used in bulk-heterojunction (BHJ) organic photovoltaics (OPVs) are discussed.
Journal ArticleDOI
Low-temperature, solution-processed molybdenum oxide hole-collection layer for organic photovoltaics
Scott R. Hammond,Jens Meyer,N. Edwin Widjonarko,Paul F. Ndione,Ajaya K. Sigdel,Andres Garcia,Alexander Miedaner,Matthew T. Lloyd,Antoine Kahn,David S. Ginley,Joseph J. Berry,Dana C. Olson +11 more
TL;DR: In this paper, a low-temperature solution-processed molybdenum oxide (MoOx) hole-collection layer (HCL) was developed for organic photovoltaic (OPV) devices that is compatible with high-throughput roll-to-roll manufacturing.
