Scientific mapping and data analysis of the research landscape in perovskite solar cell technology

Extensive literature on Perovskite solar cell technology (PSCT) has become widespread as technology enables more innovations in the field. Despite efficient platforms like Web of Science, Scopus, Google Scholar, and others, challenges persist for new researchers in search of synchronized key information in the PSCT field. Inefficiencies arise from scattered data, hindering the research cycle for the new researchers. Moreover, policy-making and planning by the stakeholders (Government, Academia, and Industry) in research and innovation rely on data-driven approaches, emphasizing the need for identifying key information to mitigate technological risks in the field of PSCT. This research gap is addressed by the effective extraction of key knowledge from the fragmented literature of PSCT. To achieve this, a comprehensive scientific mapping is conducted via bibliometric analysis, encompassing a collection of 11,092 scientific publications. All relevant data that can bridge the mentioned research gap has been meticulously extracted and analyzed from the mentioned literature which involves the trend from inception, main contributors (countries, researchers, and production sources) to PSCT, detailed keywords, and thematic analysis. The key results reveal that People's republic of China, the USA, and India significantly contribute to PSCT research, leading in publications and citations. “ACS Applied Materials and Interfaces” followed by “Journal of Materials A,” “Solar RRL,” and “Advanced Energy Materials.” Keyword analysis identifies four clusters: “stability,” “efficiency,” “optical properties,” and environmental concerns. The trends show the perspective of the PSCT sub-areas, like stability for commercialization, innovative methods for performance improvement, and considerations for lead-free options.
