Polarized X-ray scattering measures molecular orientation in polymer-grafted nanoparticles

Autor: Subhrangsu Mukherjee, Jason K. Streit, Eliot Gann, Kumar Saurabh, Daniel F. Sunday, Adarsh Krishnamurthy, Baskar Ganapathysubramanian, Lee J. Richter, Richard A. Vaia, Dean M. DeLongchamp

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-10 (2021)

The orientation of polymer chains in the corona of polymer-grafted nanoparticles has never been measured. Here, the authors use polarized resonant soft X-ray scattering to measure local chain orientation in polystyrene grafted gold nanoparticles and

Sub-picosecond charge-transfer at near-zero driving force in polymer:non-fullerene acceptor blends and bilayers

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-10 (2020)

It has been commonly believed that the driving force at the donor-acceptor heterojunction is vital to efficient charge separation in organic solar cells. Here Zhong et al. show that the driving force can be as small as 0.05 eV without compromising th

Efficient upgrading of CO to C3 fuel using asymmetric C-C coupling active sites

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-7 (2019)

Catalysts for CO electroreduction have focused on Cu, and their main products have been C2 chemicals. Here authors use the concept of asymmetric active sites to develop a class of doped Cu catalysts for C-C coupling, delivering record selectivity to

Higher order effects in organic LEDs with sub-bandgap turn-on

Autor: Sebastian Engmann, Adam J. Barito, Emily G. Bittle, Noel C. Giebink, Lee J. Richter, David J. Gundlach

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-10 (2019)

Conflicting mechanisms have been proposed to explain the sub-bandgap turn-on behaviour of heterojunction organic light-emitting diodes (OLEDs). Here, by probing and modifying the OLED heterojunction, the authors show that band-to-band recombination i

A simple and robust approach to reducing contact resistance in organic transistors

Autor: Zachary A. Lamport, Katrina J. Barth, Hyunsu Lee, Eliot Gann, Sebastian Engmann, Hu Chen, Martin Guthold, Iain McCulloch, John E. Anthony, Lee J. Richter, Dean M. DeLongchamp, Oana D. Jurchescu

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-8 (2018)

Minimizing contact effects in organic semiconductor-based devices is a key step toward the development of a low-cost technology for next-generation electronics. Here, the authors reduce contact resistance in organic devices by engineering electrodes

Toward Fast Screening of Organic Solar Cell Blends

Autor: Artem Levitsky, Giovanni Maria Matrone, Aditi Khirbat, Ilaria Bargigia, Xiaolei Chu, Oded Nahor, Tamar Segal‐Peretz, Adam J. Moulé, Lee J. Richter, Carlos Silva, Natalie Stingelin, Gitti L. Frey

Publikováno v: Advanced Science, Vol 7, Iss 15, Pp n/a-n/a (2020)

Abstract The ever increasing library of materials systems developed for organic solar‐cells, including highly promising non‐fullerene acceptors and new, high‐efficiency donor polymers, demands the development of methodologies that i) allow fast
