摘要

人们对使用室内光伏(IPV)设备为物联网应用、低功耗通信和室内环境传感供电的兴趣与日俱增。为了实现 IPV 技术的商业化,设备性能测量必须符合相关的标准化规范。我们介绍了一种新型 IPV 设备测量系统,该系统结合了数字光处理 (DLP),可在所有要求的照度水平下提供光谱不变的光源,符合 IEC TS 62607-7-2:2023 中规定的室内标准测试条件。我们根据光谱重合度、时间稳定性和样品平面的不均匀性等要求对 DLP 系统进行了评估。我们展示了测量结果,以确定系统的分类状态以及 DLP 系统的独特优势,即在所有照度水平上都能获得稳定的光谱轮廓和高度的均匀性。这是首次报道基于 DLP 技术的 IPV 设备测试测量系统,这项工作的分类方法可作为一个范例,用于根据最新的 IEC TS 62607-7-2:2023,对实验室环境中的室内光模拟器进行分类。

Performance measurements for indoor photovoltaic devices: Classification of a novel light source
There is an increasing interest in using indoor photovoltaic (IPV) devices to power Internet of Things applications, low power communications, and indoor environmental sensing. For the commercialization of IPV technologies, device performance measurements need to conform to the relevant standardized specifications. We present a novel IPV device measurement system that incorporates digital light processing (DLP) to deliver a spectrally invariant light source at all required illuminance levels, as specified by the indoor standard testing conditions in IEC TS 62607-7-2:2023. We evaluated the DLP system according to requirements for spectral coincidence, temporal stability, and non-uniformity at the sample plane. We demonstrate the measurements to define the classification status of the system and the unique benefits of the DLP system that allow a stable spectral profile and high levels of uniformity across all illuminance levels. This is the first reported measurement system for IPV device testing based on DLP technology, and the classification methodology of this work can be used as an example for the classification of indoor light simulators in laboratory environments based on the latest IEC TS 62607-7-2:2023.
