Organic-inorganic hybrid perovskite solar cells (PeSCs) have attracted great attention as next-generation photovoltaics due to their high efficiency, low manufacturing cost, facile solution-processability, light weight, and mechanical flexibility. Since the advent of the PeSCs, the researchers have devoted a lot of efforts to improve the PeSC-performance, boosting the progress in the power conversion efficiency (PCE) of over 20%. This progress has gradually shifted the focus of the PeSC research to study of reliability and cost-effectiveness of the PeSCs. In this study, we systemically investigate these research trends of the PeSCs for their sustainable development and market entry by using ‘Social Network Analysis (SNA)’. For SNA data, SCI(E) papers on PeSCs published from 2009 to 2017 are collected, and classified into two categories (research fields and commercialization factors). Next, we conduct respective networks visualization, networks topological analysis, and node centrality analysis. With the aid of SNA, the technology and knowledge networks (flows) for PeSC research fields are investigated in terms of countries, research institutions, research fields, and commercialization factors.
