Today I found a new blog 
(only a few days old) on hybrid and organic photovoltaics by Juan Bisquert, Professor for Applied Physics in Castelló de la Plana, Spain. I know him as author of interesting papers, a recent one being the review-like article on a rather fundamental view on diffusion and its different interpretations in disordered materials [Bisquert 2008]. Also, allow me the unrelated remark (personal interest, so to say;) that his university seems to be just within a wine region, similar to my home of choice.
As fellow blogger with common interest:
Welcome!
I am looking forward to reading your posts.
Carsten
Update 20.2.2009: At the same time, another new blog from the same university started; same topic, different style.
Notes on Disordered Matter 
Carsten, thank you for the quote. Nano-organic photovoltaics is raising a lot of interest, so I feel it is important to extend the discussion not just within the academic world. You have written many interesting things here in your blog, so I see you saved me a lot of work. Congratulations, and good luck with the polarons, they are very elusive.
