一种光伏器件的衰减方法及其衰减测试方法
摘要：
本发明涉及一种光伏器件的衰减方法，所述方法包括向光伏器件注入电流，进行电致衰减；所述注入电流至少具有一个大电流和一个小电流；所述大电流≥5A，所述小电流＜5A。本发明采用大电流和小电流的方式对光伏器件进行衰减，能够在较短时间内获得衰减彻底的效果，为量产监控起到保障。本发明光伏器件的衰减周期短，能够及时、准确监控基于多晶PERC电池片的光伏器件的衰减状况，对衰减监控起到决定性作用。结合本发明提供的衰减方法进行的衰减测试，能够更真实的模仿基于多晶PERC电池片的光伏器件在使用过程中的衰减情况，提供产品质量的控制。
摘要（英）：

The invention relates to an attenuation method for photovoltaic devices. The method comprises the step of injecting currents into a photovoltaic device for electrically induced attenuation, wherein the injected currents at least include a large current not less than 5A and a small current less than 5A. The method employs large currents and small currents to perform attenuation on photovoltaic devices, so that the effect of thorough attenuation can be achieved in short time and volume production monitoring is guaranteed. According to the invention, the photovoltaic device attenuation period isshort, which plays a decisive role in performing attenuation monitoring, and thus the attenuation status of photovoltaic devices based on polycrystal PERCs can be monitored timely and accurately. Attenuation tests performed based on the attenuation method provided by the invention can truly imitate the attenuation condition of photovoltaic devices based on polycrystal PERCs in a using process, sothat product quality control can be provided.
