RelaxEU proposal submitted today, acceptance rate last year was 7%… so something for relaxing is required;-) As everybody relaxes differently, you have the choice of looking at the photograph or watching the video Bad project (disclaimer: a parody – thanks to Thiemo for the link).

For unrelated reading, but following up some other notes on publishing and peer review (see overview of posts here), an insightful post by Cameron Neylon: What is it with researchers and peer review? or; Why misquoting Churchill does not an argument make. If you are researcher, peer review is (and will remain) important. Therefore, staying up to date is not only interesting (e.g., you get to see the real Churchill quote;) but also useful to see its pros and cons more clearly. Interesting may be this Nature Materials editorial on Transparency in peer review (free with registration). Out of curiosity I just checked: I reviewed 21 papers in 2010, so a couple more than I (or a coauthor) actually submitted, but a lot less than I was asked to review…

A happy and successful new year to you! It is almost three years since I started this blog, this being the 69th post. A lot happened in this time, also for me: both personally (as some of the long term readers now;-) and professionally (despite still being in Würzburg;-). Golden Pavilion (Kinkaku-ji) So, let me thank you, valued reader – and comments contributor, an active participation which I highly appreciate!

Many things I want to write about I have not had time to handle in the recent months. For now, let me start with just briefly revisiting what I have written. Hints of what I will add in the coming weeks and months are to come soon (soon meaning: worst case mid February, as one proposal is submitted by then, lecture is finished and project meeting / seminar talk marathon “finished”;-).

Find the overview below. Continue reading “2011”

New Record for Organic Solar Cells and other stuff

Solarmer did it again: 8.13% power conversion efficiency, certified by NREL, were anounced at the currently running SPIE Optics and Photonics conference in San Diego.

I am also here, my talk will be on wednesday afternoon – but do not expect any breakthroughs in terms of performance from me:-) Maybe there will be more news here in the days to come.

Foothill Mountains - Russian RidgeIn June and July, I was visiting scientist in the group of Mike McGehee at Stanford University for five very interesting weeks. Thanks again for hosting me, and for the interesting discussions we had! I also had a brief visit to PARC, the Palo Alto Research Center, for an interesting discussion with Robert Street about the photocurrent in organic solar cells. We finally agreed to disagree on some issues, but from my point of view, that’s absolutely fine.

During my Stanford visit, there was fortunately time enough for hiking in the Foothill Mountains as well! Highly recommended. Thanks to Andreas and Verena as well as Matthias for getting me started.

HOPV2010 conference symposium and minor news

Three weeks ago I participated in a very nice Conference on Hybrid-Organic Photovoltaics (HOPV2010) in Assisi, ItalyAssisi. Juan Bisquert, member of the Scientific Commitee, had asked me to organise a discussion panel on Carrier lifetime in bulk heterojunction solar cells. Indeed, a lively exchange of concepts and ideas between the panel – James Durrant, Germa Garcia Belmonte, Gytis Juska and myself – and the audience developed. I would like to thank the organisers, the panelists and the participants of this symposium once again: it was great! I am not sure if I will be able to summarise some of the discussion highlights here, considering that even this note took me 20 days… but I strive to improve;-)

Short note: my short review finally came online. Coauthors are Vladimir Dyakonov and Christoph Brabec. In case you have access to IEEE, find the paper here.

Be aware of ads…

I finished the Review article I was Schlumpf1recently talking about. If you are interested, the preprint can be accessed here (in a few hours, 20:00 EST according to arXiv, so be patient;-) [Update 2nd March 2010] It’s up:-)

Reviews seem to be pretty subjective, and I am sure there are many omissions, but hopefully not too many inconsistencies. If there are any particular things you do like or do not like, or which are plain wrong: I am happy about every bit of constructive criticism! I submitted the article to Rep. Prog. Phys. It will be peer-reviewed, and I am pretty sure the referees’ comments will make the current version much less final as I’d like it to be;-)

[Update 25.6.2010] The review was accepted after some minor revisions, and is scheduled for publication by Rep. Prog. Phys. in September (2010).

Science talking vs doing – and status

There is an interesting post on The Scholarly Kitchen on Talking About Science vs. Doing Science, a critical view on Web 2.0 for Scientists.

Every second spent blogging, chatting on FriendFeed, or leaving comments on a PLoS paper is a second taken away from other activities. Those other activities have direct rewards towards advancement.

Actually, this is one of the reasons for the low activity in recent months: I just do not have time for the blog right now – I believe I can write again end of March or so. Nevertheless, I am active, having written proposals (1 won, 1 open) as well as two review-like papers. One of them is on Organic Bulk Heterojunction Solar Cells, the other on the Role of the Charge Transfer State for Organic Photovoltaics. Writing a third one right now… Once they are published (if they ever are), I will link to them. You are likely to find some figures etc familiar from the blog… and finally something to properly reference :-)

[Update 25th March 2010] 2nd proposal won as well;-) Also, the CT review was accepted by Adv Mater: if you are interested in the preprint, drop me a line.

Personal news: married again…

… and the best news is, it is the same lady;-)

Anja and Carsten, 11072009 (Photo Peter Leutsch).jpg On the 11th of July 2009, Anja and I celebrated our church wedding. After the civil wedding last December in my home town Wuppertal, we now married in Anja’s home village Schwebheim in Lower Frankonia. It was a wonderful ceremony, and a very nice festivity afterwards (I believe… but I might be biased;-).

The only reason I am already back at my computer is that the beginning of our honey moon is somewhat delayed, as both of us have very interesting but also demanding jobs. Well, postponed is not abandoned!

All the best,
