IEC TS 63202-3:20 23描述了用于实验室和大规模生产应用的晶体硅双面光伏(PV)电池的电流-电压(I-V)特性的测量程序。 除了IEC 60904-1中描述的要求之外，本文件旨在用于单个未封装双面PV电池的测量，与更适用于封装PV器件的IEC TS 60904-1-2不同。还定义了对双面参考电池和太阳模拟器校准的具体要求，为所提出的方法提供有用的指导。

IEC TS 63202-3:2023 describes procedures for the measurement of current-voltage (I-V) characteristics of crystalline silicon bifacial photovoltaic (PV) cells for both laboratory and mass production applications.
This document is intended to be used for measurement of individual unencapsulated bifacial PV cells, in addition to the requirements described in IEC 60904-1 and differentiating from IEC TS 60904-1-2 which is more applicable to encapsulated PV device. Specific requirements on bifacial reference cells and calibration of solar simulators are also defined to provide useful guidance for the proposed methods.
