2、The International Energy Agency(IEA),founded in 1974,is an autonomous body within the framework of the Organization for Economic Cooperation and Development(OECD).The Technology Collaboration Programme(TCP)was created with a belief that the future of energy security and sustainability starts with gl

3、obal collaboration.The programme is made up of 6.000 experts across government,academia,and industry dedicated to advancing common research and the application of specific energy technologies.The IEA Photovoltaic Power Systems Programme(IEA PVPS)is one of the TCPs within the IEA and was established

4、in 1993.The mission of the programme is to“enhance the international collaborative efforts which facilitate the role of photovoltaic solar energy as a cornerstone in the transition to sustainable energy systems.”To achieve this,the Programmes participants have undertaken a variety of joint research

5、projects in PV power systems applications.The overall programme is headed by an Executive Committee,comprised of one delegate from each country or organisation member,which designates distinct Tasks,that may be research projects or activity areas.The 28 IEA PVPS participating countries are Australia

1. **IEA PVPS Task 13**:聚焦光伏组件的可靠性、性能及二次利用(2nd Life),通过修复、翻新和延长寿命支持循环经济,减少废弃物。 2. **修复策略**: - **背板修复**:涂层(如聚氨酯、硅胶)可修复裂纹并恢复绝缘电阻,现场应用超30个月稳定。 - **互联/焊点修复**:现场树脂密封或更换旁路二极管,成功率75%-90%。 - **玻璃修复**:树脂填充裂缝,经湿热老化后性能损失仅4%-4.7%(未修复模块为7.8%)。 3. **二次利用挑战**: - **经济性**:新组件成本下降,修复劳动密集,仅特定场景(偏远地区、政策支持)可行。 - **标准化缺失**:缺乏统一的再认证和测试标准,影响市场接受度和融资可行性。 4. **案例验证**:SolarCycle和2nd Cycle项目显示,二次利用系统可稳定发电,但模块异质性和认证仍是瓶颈。
