CHEETAH is an FP7 integrated research proje ct on photovoltaics funded by the European Commissio n and was initiated by EERA PV. This project is struc ured into two type of activities: Coordinative and Support actions (CSA) and Joint Research activities (JRA). Th e CSA focuses on the creation of a long term collabo r tive platform by developing tools for knowledge sharing , e-learning platforms for training and education, mobility between researchers, efficient use of infrastructur es and promoting best practices and standards. The JRA focuses on developing new concepts and technologies for waferbased crystalline silicon PV (modules with thin cel ls < 100 micron), thin-film PV (advanced light management) a nd organic PV (very low-cost barriers), resulting i reduced cost of environmentally benign/abundant/non-toxic m aterials and increased module performance. This pap er gives a summary of the main achievements of this project fo r he two categories of activities.
