Bibliometric Analysis of Research Trends on Quantum-Dot-Sensitized Solar Cells over Two Decades

Many years after the introduction of quantum-dot-sensitized solar cells (QDSSCs), publications related to it have been widely disseminated in scientific archives. In this study, a bibliometric analysis was conducted to examine the bibliographic content of publications indexed in the Science Citation Index Expanded database from 2000 to 2021. Over the past two decades, 1557 articles have been published in the field of QDSSCs, covering studies on the photoanode, cathode, and electrolytes of the system. The most active journal, Electrochimica Acta, has published 6.48% of the total number of publications. The three most productive nations are China, South Korea, and India, accounting for 47.4%, 13%, and 9%, respectively, of publications from the top 20 nations. Through keyword analysis, our findings suggest that scholars have focused on controlling the optical and electrochemical properties of active materials, studying power conversion mechanisms, and investigating other internal kinetic mechanisms of QDSSCs. The authors and institutions are also classified based on their scientific performance over the past two decades to determine the intellectual base. This study assesses the general progression in QDSSC research and may provide baseline information to help scholars identify research trends in the field of QDSSCs.
