Efficiency plays an essential role in improving solar cell quality and affordability. Single-junction perovskite solar cells’ (PSCs’) power conversion efficiencies (PCEs) have grown drastically over the past ten years, reaching 26.1% and gradually approaching their maximum efficiency. The PCE of multi-junction tandem solar cells (TSCs) is outstanding, exceeding the single-junction cells’ 33% limit. Over revolutionary photovoltaic techniques, the TSC provides excellent efficiency, stability, cost-efficiency, and an effortless manufacturing process due to their complementary properties of both PSCs and organic solar cells (OSCs). Regarding the performance of the devices, the cost of fabrication, and the variety of usage, perovskite organic tandem solar cells (POTSCs) are going to surpass existing TSCs. In the last few years, the development of OSCs has been significantly sped up by the formation of Y6 series non-fullerene acceptors, which have led to a record advancement in POTSCs. This investigation opens a pathway by outlining the shift from single junction solar cells to TSCs, then a detailed review of the efficient PSCs, and it also discusses major features, including structural and numerical properties, performance, losses, and stability over time. This study explores the basics of perovskite solar cells along with recent technologies and approaches that will lead to a better understanding of the field of TSCs.
