We've had an organic electronics (OE) journal club in the physics department at NC State for about four years now that has moved this summer to the ORaCEL facilities on Centennial campus. It all started after discussions between Ade, Dougherty, and Gundogdu about the meaning of the word "polaron" and whether it is used consistently in the organic electronics literature. We decided we'd better have a regular meeting to clarify this and the journal club was born. I think it is safe to say that we've all learned a lot about polarons, excitons, etc in the intervening years. We still often revert to our initial discussion: What IS a polaron? What do THESE authors mean by polaron? I'll hopefully have science discussions related to this in future posts, though Doug Natelson has pretty much covered the non-technical points about the topic in his blog post here.
More recently, the journal club has been led by graduate students and post-docs and has occasionally featured delicious pizza. In the summer of 2014, after some significant student turnover (PhD's awarded !) , the newer students organized a series of tutorials covering the basics of organic electronics. Topics included:
- Organic materials and how to make thin film samples
- Molecular Orbital Theory
- Basic organic devices (OPV's, OTFT's, OLED's) and device measurements
- Singlet and Triplet excitons
- Interfacial band alignment
We're now back in the mode of presenting important new articles and we realized we want a written record. So far, the following articles have been presented:
Fill Factor in Organic Solar Cells (presented by Andy Barrette)
Role of Spin in Kinetic Control of Recombination in Organic Photovoltaics (presented by Masoud Ghasemi)
The first blog post will summarize key points (from my perspective) from the second paper.
