An innovation model providing a solution for climate change and sustainable economic growth is required. In this scenario, renewable energy is one of the most promising technologies. Its research -requires a considerable amount of R&D expenditure and various core technologies. Therefore, international research collaboration is effective for prompt and efficient development. With countries and organizations contributing to the rapid growth of knowledge, the meta-structure of international research and collaboration has become ambiguous. This paper aims to establish a knowledgebase that can help prepare international research collaboration policies. This paper demonstrates research capacity and international research collaboration in solar and fuel cell technologies, using MAPs gathered from 68,000 research papers. The two technologies are compared and international research collaboration is analyzed. A valley of research collaboration in Asia and a gap between the research collaboration structures of the two technologies are identified, and the context of this gap is discussed.
Date of Conference: 7-10 Dec. 2010
