(Erfurt, 21.01.2013). On the 17th -18th of January 2013 the leading European Photovoltaics Clusters met in Erfurt (Germany) for the Kick-Off of SOLARROK, a project funded within FP7 Capacities, “Regions of Knowledge”. By SOLARROK, seven European regions join their forces to strengthen the Photovoltaics (PV) innovation-driven research and industry. The future of the PV sector will be taken into focus starting from a regional level to a transnational action. Central issue of the European project is to develop and integrate a Joint Action Plan as a strategic instrument for the PV Solar Energy. The basis will be set in a close dialog with all triple helix stakeholders (business, research, public authorities).
