Title:
太陽電池を用いた電磁波吸収方法
Document Type and Number:
Japanese Patent JP4009893
Kind Code:
B2
Abstract:
An electromagnetic-wave absorbing method using a solar cell or cells is provided, whereby there comes about essentially no reflection of electromagnetic waves by the solar cell or cells without impeding solar light power generation thereby. A solar cell module (10) may be constructed from a plurality of solar cells (1) wherein respective upper electrodes (2, 2) are electrically connected together by a conductor (7) and a common lower electrode (6) is used. So that any possibly reflected wave may be absorbed, the impedance of the solar cells to electromagnetic waves incident thereon is matched to an electromagnetic-wave characteristic impedance by adjusting the number of the solar cells (1) arranged or the way in which they are arranged or by connecting a capacitor (13) across a pair of output terminals (8, 9) of the module. Alternatively, a plurality of such solar cell modules (10) different in shape and/or surface area are arranged in such a manner that reflected wave being reflected by the individual solar cell modules differ in phase so that they may be canceled one by another. Alternatively, it is possible to form an electromagnetic wave reflector (54, 57) on a rear surface of the solar cell (1) or on a wall surface over which it is to be mounted and a reticular electromagnetic-wave reflector (55) on a top surface of the solar cell, in an arrangement such that a reflected wave being reflected by the electromagnetic-wave reflector (54, 57) on the rear surface or the wall surface and a reflected wave being reflected by the reticular electromagnetic-wave reflector (55) may interfere with each other and be thereby cancelled each by other.
