IEC TR 63228:2019总结了新兴光伏技术（特别是OPV、DSC和PSC器件）性能评估的当前观点。这些器件对现有IEC 60904系列标准下的精确测量提出了一些挑战，这些标准是在硅片太阳能电池的背景下开发的。对于不同的设备，这些挑战可能不同，但通常它们是由于以下一个或多个原因而出现的:-性能随时间的不稳定性；-不寻常的光谱响应性；-装置尺寸小；测温困难；-对外部刺激的瞬时响应；-光学干涉效应；和-对辐照度的非线性电流响应。这些挑战可能导致实验室测试中的细胞输出与实际应用中观察到的输出显著不同。该报告的主要重点是测量电流-电压（I？V）在照明下的关系，以确定设备输出功率或功率转换效率。在适当的情况下，报告参考了IEC 60904系列，该系列描述了测量所有光伏设备性能的标准方法。该报告还参考了寻求适应OPV、DSC或PSC设备的现有公布标准。

IEC TR 63228:2019 summarises present perspectives on the performance evaluation of emerging PV technologies, specifically OPV, DSC and PSC devices. These devices present some challenges for accurate measurement under the existing IEC 60904 series of standards, which were developed in the context of silicon wafer solar cells. These challenges can be different for different devices, but in general they arise due to one or more of the following:
- instability in performance over time;
- unusual spectral responsivity;
- small device size; difficulty in measuring temperature;
- a transient response to external stimulus;
- optical interference effects; and
- a non-linear current response to irradiance. These challenges can lead to the cell output in laboratory testing being significantly different to the output that would be observed in a real application.

The primary focus of the report is measurement of the current-voltage (I？V) relationship under illumination for the purpose of determining the device output power, or power conversion efficiency. Where appropriate, the report makes reference to the IEC 60904 series which describes the standard approach to measuring the performance of all PV devices. The report also references existing published standards that seek to accommodate OPV, DSC or PSC devices.
