访问： 阿里云 2022“上云采购季 ” 百款云产品最低0.24折起 视频截图（来自：MIT） 预计到 2030 年的时候，全球光伏发电占比或可达到 10%，且其中大部分可能位于阳光充裕的沙漠地区。 然而光伏面板上特别容易积聚灰尘，可在短短一个月内让输出效率减少多达 30%，因而定期清洁对太阳能部署至关重要。 据估计，当前每年需要消耗约 100 亿加仑的水来清洁太阳能电池板 —— 如此高的消耗，可满足多达 200 人的饮用水需求。 但在尝试无水清洁方案的时候，往往需要动用相当密集的劳动力、并且会导致表面出现不可逆的划痕损伤（同样会导致效率降低）。 How to clean solar panels without water – MIT（ via ） 现在，MIT 研究团队设计了一种适用于光伏面板、或热电太阳能镜面的无水 \/ 非接触式自动清洁方法，可显著减少灰尘引发的问题。 具体说来是，新系统使用静电排斥让灰尘颗粒分离、并从目标表面飞走，而无需动用水或刷子。 研究配图 – 1：灰尘堆积对太阳能输出效率的影响 在激活该系统的时候，只需通过一个位于面板正上方的简单电极、将电荷传递给灰尘颗粒，然后让它们被施加到面板本身的电荷给排斥。 如需结合自动化清洁方案，亦可加装基于电动机和侧面导轨的简单方法。感兴趣的朋友，可查阅 2022 年 3 月 11 日出版的 Science Advances 期刊。 研究配图 – 2：利用静电电荷感应方法来除尘 MIT 工学院研究生…
