Brief Ad: Organic Solar Cell Review Online [Update]

Sunset in UmbriaIf interested, find it here (Reports on Progress in Physics 73, 096401 (2010)). Included: how do bulk heterojunctions and bilayers work, how to improve the performance, how to mass print, and a brief section on the cost. I am happy it is finally “on air”:) Free from IOP for the first 30 days, if you register. Otherwise, choose the arXiv version or drop me a line. As I am on vacation, expect some delay…

[Update 30.8.2010 ] Back from vacation for already a week: was very relaxing:) In order to avoid another “ad post”, I just extend this one a bit: the progress report on charge transfer complexes (submitted to Advanced Materials already in February) is now published online. You will not find this one on arXiv, so if you cannot access it, ask me to send you the preprint. As always, I am interested in your opinion and/or criticism!

Several people speaking

Adding to my selection of sayings (previously here, here and here;-) Not always very deep, but mostly quite nice.

Stanford University
Jack London:

You can’t wait for inspiration. You have to go after it with a club.

William Gibson:

The future is here. It’s just not evenly distributed.

Niels Bohr:

I try never to write more clearly than I am able to think.

John von Neumann:

There is no sense in being precise when you don’t even know what you are talking about.

Henry Ford:

If I’d listened to customers, I’d have given them a faster horse.

Peter Drucker:

What everybody knows is frequently wrong.

Do not believe that it is very much of an advance to do the unnecessary three times as fast.

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.
