无玻璃、重量轻的光伏模块有可能在建筑集成和车辆集成应用中实现太阳能的新用途。无玻璃模块具有重量减轻、安装解决方案成本降低和运输成本降低的优点。乙烯基聚四氟乙烯（ETFE）通常被认为是一个合适的候选人，以取代玻璃作为前盖片材料在模块制造。在这篇文章中，我们报告了它的光学，化学，自清洁和形态学特性。耐用性是一个关键问题，特别是对于建筑一体化应用，因为恶劣的条件下普遍存在的户外。我们报告的影响序列的环境压力测试（紫外线照射，湿热）。模块盖材料也需要定期清洁，这可能会导致表面损坏。我们报告使用线性磨损测试来评估ETFE对各种磨料的耐磨性。研究结果提供了有用的数据，说明了用耐用聚合物替代玻璃用于太阳能电池组件前板的优点和缺点。
Glass-free, lightweight, photovoltaic modules have the potential to enable new uses of solar in building integrated and vehicle integrated applications. Glass-free modules have the advantages of reduced weight, lower-cost mounting solutions, and reduced transportation costs. Ethylene tetrafluoroethylene (ETFE) is usually considered a suitable candidate to replace glass as the front cover sheet material in module fabrication. In this article, we report on its optical, chemical, self-cleaning, and morphological properties. Durability is a key issue, especially for building-integrated applications since harsh conditions are prevalent outdoors. We report on the effect of sequences of environmental stress tests (UV exposure, and Damp Heat). The module cover material is also subject to regular cleaning, which can cause surface damage. We report on the use of linear abrasion testing to assess the abrasion resistance of ETFE to a variety of abrasive materials. The results provide useful data on the advantages and disadvantages of replacing glass with a durable polymer for front sheets in solar modules.
