Annual Research Review of Perovskite Solar Cells in 2023

Abstract Perovskite (PVK) solar cells (PSCs) have garnered considerable research interest owing to their cost-effectiveness and high efficiency. A systematic annual review of the research on PSCs is essential for gaining a comprehensive understanding of the current research trends. Herein, systematic analysis of the research papers on PSCs reporting key findings in 2023 was conducted. Based on the results, the papers were categorized into six classifications, including regular n-i-p PSCs, inverted p-i-n PSCs, PVK-based tandem solar cells, PVK solar modules, device stability, and lead toxicity and green solvents. Subsequently, a detailed overview and summary of the annual research advancements within each classification were presented. Overall, this review serves as a valuable resource for guiding future research endeavors in the field of PSCs.
