While the study provides a valuable framework for understanding ionic effects in perovskite devices, the assumptions regarding ion mobility uniformity across the bulk material warrant further scrutiny. Could the authors clarify whether spatial heterogeneity in ion mobility, especially near interfaces, was considered in the simulations? Additionally, the exclusion of dynamic environmental conditions (e.g., temperature fluctuations) may limit the real-world applicability of the findings. Could these factors be addressed in future investigations to enhance the robustness of the method?
