Solar Energy and Nano materials for Clean Energy Development

This special issue on Solar energy and nano materials for clean energy development is composed of selected, full-length versions of papers presented during the international Solar 09 conference that was held in the fascinating historical city of Luxon. The conference gathered scientists from 26 countries, to discuss outstanding research on a multitude of topics and disciplines. As was pointed out by Professor Paul Barbara from the University of Texas in Austin at the opening session of the conference, this medium-sized conference offered the unique opportunity to learn and exchange scientific issues from distinct disciplines that have one main thing in common, solar photons. This exceptional opportunity to learn about other fields of research not only required particular didactic skills form the speakers, but also demanded special attention and openness from the audience.
