Self-powered electrodynamic dust removal for sustainable solar panels using triboelectric nanogenerators

Maintaining the efficiency and longevity of solar panels relies on effective dust management. While electrodynamic screen (EDS) technology is a promising solution, its reliance on high-voltage power sources can compromise overall solar panel efficiency. In this study, we introduce an innovative approach that harnesses wind-driven rotating triboelectric nanogenerators (RTENGs) to power EDS systems, enabling autonomous dust removal from eco-friendly solar panels. We conducted precise optimizations of the RTENG's structure, electrode design, and the dielectric material of the EDS plate to maximize system performance. Our results establish a direct relationship between RTENG power output and solar panel performance, achieving efficiencies exceeding 90% at wind speeds of 28 m/s. This research underscores the practical viability of triboelectric nanogenerators as a sustainable power source for dust management, offering profound implications for the field of solar energy harvesting.
