“…Tatom [1] in 1967, and further developed and implemented by Masuda et al at the Tokyo University in the 1970s [2,3,4]. Since then, electroporation based techniques have been used in a very wide application range, from solar cell cleaning [5][6][7][8][9][10] to radioactive dust manipulation in fusion reactors [11,12], microfluidics [13,14], control of bubbles in dielectric liquids [15], sorting and manipulating particles by size [16][17][18][19], cell transport in liquid medium [20,21] or dust reduction in professional environments in the so called electrostatic precipitators [22][23][24]. The electrostatic precipitator operation relays in the natural or induced particle charge and has been consolidated as an excellent method for the removal of particles greater than 1 µm suspended in gases, constituting the most commonly technology to clean the emission in power plants [24].…”

This paper describes the design, fabrication and characterization of a three phase floating electrodes electroportation system for dust confinement, compatible with industrial optical quality control systems. The proposed Floating Electrode Electronic Curtain (FE-EC) is composed of floating parallel wire electrodes framed by a two-layer PCB. The floating electrodes are connected to one of the synchronized three channels to generate an electric field traveling wave. The separation between the floating wire electrodes has been determined by minimizing the number of trajectories crossing the FE-EC using a numerical simulation tool. It is shown that the effect of the FE-EC in the luminosity of an industrial led luminaire can be compensated by an 1% increment in the led supply voltage. The performance of the fabricated FE-EC prototype is experimentally quantified, showing efficiencies higher than 95% in simulated relevant conditions.

“…Indoor tests show that up to 98% of the sand can be removed in tens of seconds without using neither water nor mechanical cleaning . First demonstration of particle transport using variable electric field was shown by Masuda et al This approach was used for many different applications like dust removal for lunar and Martian exploration missions or for fusion reactors, particles supply in Xerography and bubbles or blood cells motion in dielectric liquids . The naming of this approach is as numerous as the number of its applications: electric curtain, electrodynamic screen, electrodynamic dust shield, or electrostatic cleaning systems.…”

Soiling is the major cause of power loss of photovoltaics (PV) and concentrated solar power (CSP) in desert areas. Electrodynamic cleaning system (EDS) is an automatic and water‐free integrated cleaning system for mirrors or solar panels, which uses pulsed electric fields to remove dust off their surface. The first EDS field test over a long period on PV modules is reported here and shows a clear effect on soiling reduction in real conditions in Saudi Arabia. A total of 458 days of measurements is analyzed, and depending on the considered periods, performance losses due to soiling (soiling rate) can vary from −0.06%/day to −0.41%/day for a reference module, while the relative soiling rate reduction using an EDS can be up to 95.7% with an average of 32.1%. Cost calculations demonstrate an added value of the modules equipped with the EDS between 2.6 and 5.2 ¢/Wp compared with usual cleaning system, which is nearly between 10% and 20% of the module price. In addition, extended indoor tests of various electrode designs of EDS for heliostat dedicated to CSP or PV applications show a high cleaning efficiency of up to 98% with front glass thickness of more than 1 mm. A good specular reflectivity, only 4% lower than the bare reference mirror, is obtained with patterned sputtered silver in a spiral electrode design. High reliability of two types of electrode deposition is demonstrated after 200 cycles between −40°C and +85°C.
