英文摘要： Accumulation of dust can cause substantially decreased efficiency and even damage to solar cells. Previous research has suggusted that one feasible method of dust removal is high-voltage wave electric curtain.And our team's work has also confirm it. This project aims to investigate the movement pattern of dust particles under traveling-wave electric curtain and subsequent optimisation of the parameters of wave electric curtain. Firstly, the properties of the earth dust particles will be studied, includding particle size distribution, charges, ionization and polarization, Especially the electronic characteristics that is basis to study the movement rule of dust particles.Secondly,distinct element method and boundary element method will be employed to build the forced and moving model of dust particles, charged or uncharged, under the forces of electrostatic, dielectric electrophoresis, resistance and charges. As a result, we will reveal the movement pattern of the dust particles in the earth's atmosphere environment and corresponding removal mechanism. Furthermore, numerical simulation and orthogonal experiment will be conducted to investigate the relationship between the dust removal efficiency and the parameters of electric curtain, including electrical power parameters (waveform, voltage and frequency), mech
