摘要

有效的太阳能生产受到灰尘堆积的严重阻碍，这严重降低了太阳能电池板的性能。为了解决这个问题，我们开发了一种相位控制、风力驱动的三相旋转摩擦电纳米发电机（RTENG），该发电机集成了一个电动屏幕（EDS），用于自供电、单向除尘。RTENG无需外部电源即可产生高压交流电（AC），并使用精确相位控制的三相电极配置来产生移动电场，使粉尘颗粒沿单一方向移动。这种结构提高了除尘效率，特别是在低面板倾角时。相控三相RTENG-EDS系统的除尘效率分别为重量的83.48%和表面覆盖率的62.38%，分别比传统的单相系统高出1.6倍和1.13倍。此外，该系统在各种风速和面板倾角下都保持了高性能。这些结果强调了相控三相RTENG技术在推进自供电太阳能电池板清洁系统和提高太阳能收集整体效率方面的有效性。

Self-powered directional dust removal via wind-driven phase-controlled TENG for solar panel maintenance

Efficient solar energy production is significantly hindered by dust accumulation, which severely reduces the performance of solar panels. To overcome this issue, we developed a phase-controlled, wind-driven 3-phase rotational triboelectric nanogenerator (RTENG) integrated with an electrodynamic screen (EDS) for self-powered, unidirectional dust removal. The RTENG generates high-voltage alternating current (AC) without the need for external power sources and uses a precisely phase-controlled 3-phase electrode configuration to produce a traveling electric field that drives dust particles in a single direction. This configuration enhances dust removal efficiency, particularly at low panel inclination angles. The phase-controlled 3-phase RTENG-EDS system achieved dust removal efficiencies of up to 83.48 % based on weight and 62.38 % based on surface coverage, outperforming conventional 1-phase systems by factors of 1.6 and 1.13, respectively. Furthermore, the system maintained high performance across various wind speeds and panel inclination angles. These results underscore the effectiveness of phase-controlled 3-phase RTENG technology in advancing self-powered solar panel cleaning systems and enhancing the overall efficiency of solar energy harvesting.
