Impedance spectroscopy has been widely used in characterizing the electronic properties of semiconductors. Its application in the perovskite photovoltaic research is a natural extension of the well‐established methodology in the new semiconducting material. However, it turns out that the published results are sometimes very strange, difficult to interpret, or the interpretations contradict each other. It is now clear that most of these troubles stem from the dominating influence of ionic contributions. Herein, some of the published data are reviewed and the possible problems are identified, which can be reconciled by taking into account the explicit contribution of the ionic behavior.

再谈阻抗谱

阻抗谱已广泛用于表征半导体的电子特性。它在钙钛矿光伏研究中的应用是对新型半导体材料中行之有效的方法的自然延伸。但是，事实证明，发布的结果有时很奇怪，难以解释，或者解释彼此矛盾。现在很明显，这些麻烦中的大多数源于离子贡献的主要影响。本文中，对一些已公开的数据进行了回顾，并确定了可能的问题，可以通过考虑离子行为的明确贡献来加以解决。
