Comparative bibliographic analyses of the global and Japanese databases in the field of solar cell

The purpose of this research is to confirm that domestic database, in the case of J-GLOBAL, will be able to be used for strategies of science and technology in the same way as global database, such as Web of Science. Domestic databases have potentials to provide unique cutting edges, due to the custom of presenting it in local conferences before publishing it in global academic journal. In addition, differences between Japanese dataset and other language's dataset are extracted. Consequently, it was proven that J-GLOBAL can be used to identify emerging researches in the field of solar cell. As one of emerging fields, “perovskite solar cell” is detected.
