A Quantitative Analysis of the Research Trends in Perovskite Solar Cells in 2009-2019

In the last decade, unprecedented research interest in the area of perovskite solar cells (PSCs) has been observed. Undoubtedly, due to an immense increase in research activity, scientific literature related to PSCs has grown considerably. However, a comprehensive quantitative analysis of literature related to this specified field is still lacking. Herein, novel statistical analysis techniques are used and the progressive effect that published work has had on the development of PSC technology in the past 11 years (from January 2009 to December 2019), is identified using "bibliometrix" and "VOS viewer" software packages. A statistical analysis based on the annual number of publications and their citational impact is performed. Further, journals, authors, institutions, and countries are ranked according to their scientific productivity and the total number of citations gathered from their published work. A total number of 16 103 documents, consisting of research and review articles, are analyzed with subsequent scientific conclusions made. This material is of great help to new researchers in the field of perovskites, enabling them to look at all the perovskite field developments in perspective and have the data at the tips of their hands, using a single reference point in the literature search.
