| Summary: | Among the next-generation photovoltaics (PVs), hybrid organic–inorganic perovskite solar cells (PeSCs) have drawn tremendous attention from both academic and industrial communities, because of their compelling combination of high performance, high cost-effectiveness, and broader feasibility. Despite the rapid growth and importance of scientific progress in the PeSC field, there have been no systematic and bibliometric analyses of the PeSC research outputs. In this study, we systemically investigate the scientific publications of the PeSCs with bibliometric routes to map research trends and collaboration status. A total of 6,581 documents published during 2009–2018 are analyzed. For effective investigation, the commercialization factors are categorized by considering levelized cost of electricity and environmental impact; Cost, Efficiency, Stability, Scaling-up, and Public Acceptability. Furthermore, the combined bibliometric methods are employed as follows: statistical analyses of publication outputs, topic modeling based on publication abstracts with time-series and commercialization factors, and social network analysis of co-authorships at institute level. From the analyses of research trends, although the researches on Efficiency takes a large part in all periods, the researches on Scaling-up, Stability, and Public Acceptability have become more active over time. In the analyses of co-authorship network, the level of collaboration in the PeSC research is already globalized, which is led by European, Chinese, and Korean institutes. The comprehensive results not only track the changes in the PeSC field, but also provide useful information on the future direction for the market entry of the PeSCs and the next-generation PVs.
