Three weeks ago I participated in a very nice Conference on Hybrid-Organic Photovoltaics (HOPV2010) in Assisi, Italy
. 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.


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
