We actively pursue understanding the physics of organic solar cells and light emitting diodes, creating novel devices, and inventing and using new characterization methods with a particular emphasis on applications to organic devices. Our work is by its very nature interdisciplinary – spanning physics, chemistry and materials science. The group consists of a mix of graduate and undergraduate students, as well as post docs from a number of disciplines.

The Ade group citation rate has surpassed for the first time 500 citations/year in 2011 (using NCSU subscription to the Web of Science database). The total might increase slightly further as the final tally for 2011 is compiled by WoS. – A heartfelt “Thank You” to all students, posts docs and collaborators who have [...]

Postdoctoral associate, John Tumbleston, received a $500 poster award at this year’s Fall Materials Research Society meeting in Boston. Over the course of the week long meeting, 2400 posters were presented with only 16 awards given. His poster titled, “Compositional Variations in Nanoimprinted Bulk Heterojunction Organic Photoactive Layers Used in Light Trapping Device Architectures” [...]

Harald Ade was informed that he was elected to the rank of AAAS Fellow by the AAAS Council.

Congratulations Eliot. Job well done!

His talk was on “Elucidating Buried Interface Structure: The Development of Index-Matched Soft X-ray Scattering.” The Powerpoint file is available here: Eliot’s prelim presentation.

Work by the Ade research group has been featured in the 2010 ALS Spectrum. This work is 1 of just a few to be highlighted, out of a total of 600 publications in 2010. The work of former group member Cheng Wang (now at ALS) is also featured in the publication.

Graduate student Jaewook Seok has graduated and is now working for Intel. Congratulatins Jaewook!

Undergraduate student Anne Watson and graduate student Terry McAfee joined the group. Post docs John Tumbelston and Wei Ma join the research group. Welcome on-board!

Postdoc Brian Collins gave a highlight talk at the Plenary Session of the 2011 ALS User Meeting, discribing our recent work on polarization dependent resonant soft x-ray scattering (P-SoXS and R-SoXS).  His talk was titled “Unique Contrast Mechanisms Using Resonant X-Ray Scattering: The Key to Nanoscale Insight in Organic Devices”

At the meeting H. [...]

Harald Ade and Eliot Gann travelled to Aussois France to give an Invited Presentation “R-SoXS, P-SoXS, IM-SoX, R-SoXR What does all that mean?” and contributed presentation “Index Matched X-ray Scattering, a technique to probe buried thin film interfaces” respectively at REXS 2011.

Harald’s Presentation at REXS 2011 –   Eliot’s Presentation at [...]

New Morphological Paradigm of the Organic Solar Cell

Our recent work measuring fullerene miscibility in polymers has been highlighted at the Advanced Light Source in Lawrence Berkeley National Laboratory.  The research combines x-ray microscopy, spectroscopy and scattering to uncover the surprising result that the fullerene PCBM does not completely phase separate from [...]

Lewis Guignard is the winner of this year’s McCormick Award for Undergraduate Research in Physics for his work on PCBM diffusion in P3HT. He most recently presented his research at the APS March Meeting in Dallas. The award is presented annually to a graduating  senior in physics, recognizing outstanding undergraduate research. [...]
