传统IV特性测试通常基于标准太阳光谱，其光谱分布、光强范围与实际LED混合光源存在显著差异，导致测试结果难以真实反映电池在应用场景中的性能。文章深入探讨LED混合照明条件的钙钛矿叠层电池IV特性测试方法，以期推动钙钛矿电池在建筑一体化光伏及物联网供能等领域的产业化进程。

Traditional IV characteristic tests are usually based on standard solar spectra, whose spectral distribution and light intensity range are significantly diff erent from those of actual LED hybrid light sources, making it di fficult for the test results to truly reflect the performance of batteries in application scenarios. This paper deeply explores the IV characteristic test method of perovskite tandem cells under LED mixed lighting conditions, with the aim of promoting the industrialization process of perovskite cells in fields such as building-integrated photovoltaics and energy supply for the Internet of Things.
