Query: Insights from Device Modeling of Perovskite Solar Cells   In this perspective, we explore the insights into the device physics of
perovskite solar cells gained from modeling and simulation of these devices. We
discuss a range of factors that influence the modeling of perovskite solar
cells, including the role of ions, dielectric constant, density of states, and
spatial distribution of recombination losses. By focusing on the effect of
non-ideal energetic alignment in perovskite photovoltaic devices, we
demonstrate a unique feature in low recombination perovskite materials - the
formation of an interfacial, primarily electronic, self-induced dipole that
results in a significant increase in the built-in potential and device
open-circuit voltage. Finally, we discuss the future directions of device
modeling in the field of perovskite photovoltaics, describing some of the
outstanding open questions in which device simulations can serve as a
particularly powerful tool for future advancements in the field.
