光伏模块上的污染的存在减少了通过前盖玻璃到有源吸收器的光透射，从而降低了效率和性能。目前的污染减轻技术是昂贵的和/或无效的。然而，施加到太阳能覆盖玻璃的防污涂层具有在不连续维护的情况下长时间减少污染的潜力。本文报道了两种透明疏水涂料（A和B）在丹麦沿海室外环境中暴露24周的性能。对涂层和未涂层玻璃试样、定期清洁试样和加速实验室试验的性能进行了比较。虽然最初的结果是有希望的，水接触角和透射率值被发现连续下降，所有涂层和未涂层的试样。观察到清洁后表面起泡、膜厚度减少、表面化学变化（氟损失）和磨损损坏。每4周清洁一次的试样显示透射率恢复。降雨量和蒸发量与潮湿和含盐环境相结合的循环导致所有试样上发生胶结。具有低滚降角和高水接触角的耐磨、超疏水涂层的开发更有可能通过减少胶结的积累来提供防污解决方案。
The presence of soiling on photovoltaic modules reduces light transmission through the front cover glass to the active absorber, thereby reducing efficiency and performance. Current soiling mitigation techniques are expensive and/or ineffective. However, anti-soiling coatings applied to the solar cover glass have the potential to reduce soiling for long periods of time without continuous maintenance. This paper reports the performance of two transparent hydrophobic coatings (A and B) exposed to the outdoor environment of coastal Denmark for 24 weeks. A comparison was made between the performance of coated and uncoated glass coupons, periodically cleaned coupons, and accelerated laboratory tests. Although initial results were promising, water contact angle and transmittance values were found to decline continuously for all coated and uncoated coupons. Surface blisters, film thickness reduction, changes in surface chemistry (fluorine loss), and abrasion damage following cleaning were observed. Coupons cleaned every 4 weeks showed a restoration in transmittance. Cycles of light rainfall and evaporation combined with a humid and salty environment led to cementation occurring on all coupons. The development of an abrasion-resistant, super-hydrophobic coating with a low roll-off angle and high water contact angle is more likely to provide an anti-soiling solution by reducing the build-up of cementation.
