The workshop "Advances in photovoltaics and photocatalysis" to be held on July 21 and 22, 2011 in Garching at the Institute for Advance Study is part of the "Deutsch-Italienische Dialoge 2011", a program of the Deutsch-Italienische Hochschulzentrum / Ateneo Italo-Tedesco. The workshop will deal with two approaches to energy conversion, namely photovoltaics and photocatalysis. In particular, new generation solar cells, water splitting and CO2 reduction for solar fuel production will be discussed. In order to present a coherent overview and to maximize interaction and discussion, the workshop will have only invited contributions with a total of approximately 20 talks. A poster session will be organized for young researchers who want to present their results. Deadline for poster submission is July 8th, 2011. The workshop registration fee is 260 € (150 € for a one day attendance). A reduced student fee is available upon request. Since the number of attendees is limited, early registration is advised. No reservation will be accepted after July 15th, 2011. For registration, poster submission and workshop program please refer to www.nano.ei.tum.de/iwapp.
