ABSTRACT Organic-inorganic hybrid perovskites can be used in solar cells with a single junction to achieve more than 25.5% efficiency. Optimizing the absorber layer (perovskite film) or investigating cutting-edge device designs, such as tandem-based solar cells that combine perovskite and silicon, can improve the device's power conversion efficiency (PCE). The overall power conversion efficiency (PCE) of a combination of silicon and perovskite solar cells can be increased above the Shockley-Queisser limit, which is the theoretical efficiency limit for single-junction solar cells. Utilizing a wider spectrum of solar light allows for this. This work shows how to model and optimize a stand-alone Cs2AgBiBr6 perovskite solar cell. Then, using SCAPS-1D, it merges that model with a crystalline silicon (c-Si) solar cell to simulate a tandem assembly. The goal of the project was to place a perovskite solar cell on top of a high-efficiency c-Si solar cell with a four-terminal (4T) structure to increase its efficiency. The simulation yielded an output voltage of 1.5V and a short-circuit current density of 23.07 MA/cm² for the Cs2AgBiBr6 perovskite solar cell, which translated into a power conversion efficiency of 29.66%. The tandem arrangement exhibited a significantly higher power conversion efficiency (43.76%) than individual cells. The findings indicate that the Cs2AgBiBr6 perovskite solar cell can be used in tandem systems with c-Si solar cells to obtain very high levels of efficiency. This work offers significant new insights into the design of effective perovskite e-Si tandem solar cells |
