论文摘要
从这个角度来看，我们探讨了从建模和模拟这些设备获得的钙钛矿太阳能电池的装置物理学的见解。我们讨论影响钙钛矿太阳能电池建模的一系列因素，包括离子的作用，介电常数，状态密度以及重组损失的空间分布。通过关注钙钛矿光伏设备中非理想的能量对齐的影响，我们在低重组钙钛矿材料中展示了独特的特征 - 形成了界面的形成，主要是电子，主要是自我诱导的偶极子，从而导致内置电位和设备的开放循环电路电流效率显着增加。最后，我们讨论了佩洛维斯基特光伏电视领域设备建模的未来方向，描述了一些出色的开放问题，其中设备模拟可以作为该领域未来进步的特别有力工具。
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.
