Ni (Research Articles, 20 March 2020, p. 1352) report bulk trap densities of 10 cm and an increase in interfacial trap densities by one to four orders of magnitude from drive-level capacitance profiling of lead halide perovskites. From electrostatic arguments, we show that the results are not trap densities but are a consequence of the geometrical capacitance and charge injection into the perovskite layer.
倪（研究文章，2020 年 3 月 20 日，第 1352 页）报告了卤化铅钙钛矿的驱动级电容剖面分析得到的体陷阱密度为 10 cm 和界面陷阱密度增加一到四个数量级。根据静电学理论，我们表明这些结果不是陷阱密度，而是几何电容和电荷注入钙钛矿层的结果。
