Organometal halide perovskite-based solar cells have shown rapid improvement in their performance. One of the predominant issues that serves as a bottleneck for further improvement is the hysteresis observed in their current-voltage characteristics, as it leads to inaccurate estimation of power conversion efficiencies. While there have been many approaches to modeling hysteresis in single perovskite-based solar cells, modeling hysteresis in perovskite-silicon tandem solar cells has largely remained unexplored. We have setup simple models, using circuit-based and TCAD-based approaches, that capture hysteresis behaviour in perovskite-silicon tandem solar cells. Our simulated current-voltage characteristics using both modeling approaches, have been validated with measured characteristics from experimentally fabricated devices reported in literature.
