International Collaboration Activity Index: Case study of dye-sensitized solar cells

作者：

Highlights：

• We develop the index of ICAI to comprehensively measure the international collaboration active degree.

• We take the dye-sensitized solar cells (DSSCs) as an empirical object.

• An International Collaboration Map is formed by displaying the international collaboration network geographically.

• Three groups, each with unique collaboration features, are formed among the 84 countries or regions.
