C Perovskite–perovskite tandem solar cells (P‐TSCs) are an attractive option to overcome the limitation of Si‐based solar cells due to their ability to deposit in both the top and bottom cells by a simple solution process. Despite these advantages, the power conversion efficiency (PCE) of P‐TSCs still falls behind that of Si‐perovskite tandem devices and is highly limited by the nonradiative recombination between the perovskite and electron transport layer (ETL) interface. In this work, with the help of numerical simulations (SCAPS 1D), the influence of the various ETLs on the performance of P‐TSCs is studied. Different ETLs such as C60, PCBM, ZnO, WO3, CdSe, and In2O3, BCP are incoroprated, which directly interface with the perovskite absorber layer in top (high bandgap absorber layer) and bottom subcell (low bandgap absorber layer) of P‐TSC. The simulation analysis shows that reducing the interface surface defect density and band offsets at the ETL/perovskite interface significantly helps achieving high‐efficiency P‐TSC over 35% . Various remediation for incorporating present simulation analysis into practical devices for better‐performing P‐TSCs is also provided. The analysis provides a pathway toward understanding the reasons behind the current trend of low PCE in 2 terminal P‐TSC and achieving high‐efficiency P‐TSC solar cells.

Recently, multijunction tandem solar cells (TSCs) have presented high power conversion efficiency and revealed their immense potential in photovoltaic evolution. It is demonstrated that multiple light absorbers with various bandgap energies overcome the Shockley–Queisser limit of single‐junction solar cells by absorbing the wide‐range wavelength photons. Here, the main key challenges are reviewed, especially the charge carrier dynamics in perovskite‐based 2‐terminal (2‐T) TSCs in terms of current matching, and how to manage these issues from a vantage point of characterization. To do this, the effect of recombination layers, optical and fabrication hurdles, and the impact of wide bandgap perovskite solar cells are discussed extensively. Afterward, this review focuses on various optoelectronics, spectroscopic, and theoretical (optical simulation) characterizations to figure out those issues, especially current‐matching issues faced by the photovoltaic society. This review comprehensively provides deep insights into the relationship between the current‐matching problems and the photovoltaic performance of TSCs through a variety of perspectives. Consequently, it is believed that this review is essential to address the main problems of 2‐T TSCs, and the suggestions to elucidate the charge carrier dynamics and its characterization may pave the way to overcome such obstacles to further improve the development of 2‐T TSCs in relation to the current‐matching problems.
