Abstract: Abstract Name of the Invention: A PHOTOVOLTAIC ELEMENT WITH AN 5 INCLUDED RESONATOR A photovoltaic element comprises a semiconductor structure comprising a first layer comprised of a first semiconductor material with minimum electromagnetic damping and a second layer comprised of a second 10 semiconductor material with electromagnetic damping. An upper plane of the first layer comprises an incidence plane of an electromagnetic wave onto the semicondutor structure and the second layer continues beyond the first layer in a direction of propagation of electromagnetic radiation to receive at least a portion of the electromagnetic radiation having passed through the first layer. 15 The photovoltaic element further comprises at least one resonator comprising a first part extending along the upper plane of the first layer and a second part extending within the first layer and the second layer. The reference electrode bordering at least a portion of the second layer is coupled to the second layer in the direction of propagation of the electromagnetic wave. A photovoltaic element including a resonator is arranged on a semiconductor structure (5) that is constituted by a region without electromagnetic damping (5a), whose upper plane forms the plane of incidence (3), and a region with electromagnetic damping (5b), both regions being bound by virtual boundaries (6) of variation in material properties. At least one 2D-3D resonator (4) is surrounded by a dielectric (10) and configured on the semiconductor structure (5), with a relative electrode (11) bordering on the region with electromagnetic damping (5b). The photovoltaic element having a resonator arranged on a semiconductor structure (5) uses the structure (5) and its characteristics to set suitable conditions for the impingement of an electromagnetic wave and its transformation to a stationary form of the electromagnetic field and not to secure the generation of an electric charge. The 2D-3D resonator produces electric current or voltage, which is conducted with the help of a nonlinear component (15) to a connecting component (16). The nonlinear element (15) shapes the signal on the resonant circuit; this signal is then filtered (rectified) to a further utilizable shape. The planar and spatial resonator (2D-3D resonator) is designed in such a manner that prevents the electromagnetic wave passing through the semiconductor structure (5) from being reflected back to the 2D-3D resonator created in the structure (5). The semiconductor structure (5) does not generate a backward electromagnetic wave propagating in the direction of the impinging electromagnetic wave emitted by a source such as the Sun. The region with electromagnetic damping (5b) has the function of suppressing the reflected wave. Thus, the resonator behaves like an ideal impedance-matched component for the proposed frequency spectrum. The semiconductor structure (5) is set in such a manner that the conductivity increases in the electromagnetic damping region (5b) in the direction of the relative electrode (11), which leads to a wide resonance curve in the photovoltaic element components.
