Perovskite‐based Tandem Solar Cells

Tandem solar cells (TSCs) represent a promising route to break the Shockley–Queisser limit of single-junction solar cells. Organic–inorganic hybrid perovskite is an ideal candidate for fabricating TSCs with the superiority of excellent photoelectric properties, bandgap tunability, and low-temperature solution processability. In this chapter, we summarize the recent progress of perovskite-based TSCs, including perovskite/crystalline silicon (PVSK/c-Si), perovskite/organic (PVSK/OPV), and perovskite/perovskite (PVSK/PVSK) solar cells. Then, we introduce the emergence of multi-junction perovskite-based tandems. Subsequently, the challenges and potential strategies toward high-efficiency perovskite-based TSCs are discussed. Lastly, the conclusions and perspectives on the promising perovskite-based TSCs are provided.
