Structural Design and Performance Optimization of Perovskite/Organic Tandem Solar Cells

Single-junction perovskite solar cells have a relatively low upper limit of efficiency, making it difficult to develop them into industrialized photovoltaic cells. To improve efficiency, perovskite tandem solar cells have become a research focus. Among them, perovskite tandem solar cells can meet different performance requirements by adjusting organic materials. In this paper, by comparing key performance and other factors between perovskite-organic tandem solar cells and those of other types of tandem solar cells, the advantages, areas for improvement, and development prospects of perovskite-organic solar cells are summarized. Meanwhile, the organic layer materials in perovskite-organic solar cells, especially Indacenodithieno [3,2-b] thiophene-imidazolecore (ITIC), are summarized, aiming to sort out the development status of perovskite-organic solar cells in recent years and provide some basic information and innovative ideas for future research in this field.
