摘　　要：Clean energy is the most promising technology for sustainable growth. The development of clean energy requires a considerable amount of R ＆ D （research ＆ development） expenditure and various core technologies, and therefore, international research collaboration is necessary for prompt and efficient development. The study is aimed at establishing a knowledge base that can help to prepare international research collaboration policies for solving global challenges effectively. The authors demonstrate the research capacity and international research collaboration in solar cell and fuel cell technologies, using global research network diagrams gathered from 35,322 and 33,136 academic papers, respectively. The diagrams include the data of research competency and co-authorship. More than 6,000 institutions and 100 countries are involved in each field. Based on the diagrams, the technologies are compared and international collaboration is analyzed. A valley of research collaboration in Asia is identified for both technologies. Then, science and education policies that influence the structures are discussed.

关 键 词：Clean energy research collaboration valley of Asia co-authorship.
