摘要：
In order to investigate the mechanism of dust particles on the surface of a solar cell panel removed by the traveling- wave electric curtain, a numerical modelling approach for the dust removal using the electric curtain technology was presented based on the COMSOL Multiphysics simulation software. The dynamics model for the coupling between the three-phase traveling-wave electric curtain and the charged dust particles was established. The motion of dust particles in various cases of electrode, power, and environment parameters was studied. The influences of electrode shapes on distribution and intensity of the electric fields were analyzed for the first time. The results of numerical simulations indicate that the dust particles can be transported directionally by the three-phase travelingwave electric curtain, and the dust particles with positive charge are removed along the direction of traveling- wave propagation and through hopping, curtain, or surfing modes; however, the motion modes of dust particles and the efficiency of dust removal are dependent on numerous factors. © 2022, Solar Energy Periodical Office Co., Ltd.
