Dust removal from solar cells

摘要

A solar panel cleaning device includes a solar panel having a plurality of photovoltaic cells arranged in rows and embedded in the solar panel with space between the rows. A transparent dielectric overlay is affixed to the solar panel. A plurality of electrode pairs each of which includes an upper and a lower electrode are arranged on opposite sides of the transparent dielectric and are affixed thereto. The electrodes may be transparent electrodes which may be arranged without concern for blocking sunlight to the solar panel. The solar panel may be a dielectric and its dielectric properties may be continuously and spatially variable. Alternatively the dielectric used may have dielectric segments which produce different electrical field and which affects the wind “generated.”

1. A dust removal system, comprising:
a dielectric substrate; a first electrode embedded in the dielectric substrate; a second electrode offset relative to the first electrode; an alternating current voltage source electrically connecting the first and second electrodes and energizable to an on position; means for creating plasma along the top surface of the dielectric substrate when the first and the second electrodes are energized; and an air flow induced by the plasma to mechanically propel dust away from an object.
