标准摘要
[中文适用范围]： IEC 62788 的这一部分提供了一种测量光伏 (PV) 模块中使用的封装材料的光学透射率的方法。此过程中的标准化测量量化了封装到光伏电池的预期透射率。随后计算太阳加权透射率可以对不同材料进行比较。未风化材料的结果可用于封装制造商的数据表@制造商的材料或工艺开发@制造质量控制（材料验收）@或应用于模块性能分析。这种测量方法还可用于监测封装材料在风化后的性能，以帮助评估其耐久性。标准化测量旨在检查光伏模块@例如@内的内部区域，而不受电池边缘周围氧气扩散的影响。随后计算黄度指数可以量化耐久性并考虑外观。封装或模块制造商可以利用透射率@黄度指数@和紫外线(UV)截止波长的变化来比较不同材料的耐久性。 [外文原描述]： IEC 62788-1-4:2016 provides a method for measurement of the optical transmittance of encapsulation materials used in photovoltaic (PV) modules. The standardized measurements in this procedure quantify the expected transmittance of the encapsulation to the PV cell. Subsequent calculation of solar-weighted transmittance allows for comparison between different materials. The results for unweathered material may be used in an encapsulation manufacturer's datasheets, in manufacturer's material or process development, in manufacturing quality control (material acceptance), or applied in the analysis of module performance. This measurement method can also be used to monitor the performance of encapsulation materials after weathering, to help assess their durability.
