摘　　要：讨论了离子迁移、介电常数依赖性、内建电场、陷阱、厚度与注入势垒等对空间电荷限制电流测量方法的影响。简要介绍了一些解决措施,例如针对离子迁移问题可以使用脉冲空间电荷限制电流法,针对缺陷问题可以使用不同的迁移率描述模型等。这为后续学者更加精确地使用空间电荷限制电流法测量钙钛矿迁移率提供参考。The effects of ion migration,dielectric constant dependence,built-in electric field,trap,thickness and injection barrier on space charge limited current measurement were summarized,and some solutions were briefly introduced,such as using pulsed space charge limited current method for ion migration problem,using different mobility description models for defect problem,etc.This could provide a reference for subsequent scholars to use space charge limited current method to measure perovskite mobility more accurately.
