A Bibliometric Panoramic Analysis on Perovskite Solar Cells by Using CiteSpace

Abstract

In the face of the increasing energy demand, perovskite solar cells (PSCs) have emerged as a third generation technology for highly efficient and low-cost photovoltaics. By using CiteSpace, this study aims to quantitatively and visually evaluate scientific literatures of research on PSCs from 2009 to 2019 by retrieving 11258 articles from the Web of Science (including SCI-Expanded and SSCI) database. PSCs have entered the stage of explosive development after 2012. Research on PSCs is a highly interdisciplinary field that covers a wide range of interests, from materials to chemistry, physics, engineering, energy & fuels, environmental science, and so on. The publications on PSCs research were primarily originated from the USA, China, South Korea, Japan, England, Germany, and Switzerland. The most productive and influential institutions, authors, journals are visually demonstrated. Finally, the keywords which represented the research hotspots and emerging trends of PSCs research areas in different periods are generated. By synthetically analyzing the keywords, the dominant hot spots of PSCs research could be concluded as “halide perovskite”, “high efficiency”, “stability”, “(diffusion) length”, “hysteresis”, “deposition”, “(charge) transport”, “recombination”, and “crystallization”. The results can not only provide a panoramic analysis of PSCs researches and give some inspirations for the researchers to do further investigations but also help policymakers to recognize and evaluate the advanced international research institutions.
