“…The essential light transmission suppression has been predicted for symmetric film. For the first time the enhancement of light transmittance through anticorrelated reliefs of thin film has been derived in our papers [15,16]. This enhancement can be explained by coupling of the surface plasmon-polariton waves on the opposite sides of the film.…”

“…Using the differential formalism [15][16][17][18], light transmittance spectra through thin metal (Au) films with nanoscale periodic texturizing on semiconductor (GaAs) substrates were calculated. Both sides of a thin film are determined by periodic profile's functions ξ 1 (r) for upper and ξ 2 (r) for lower interfaces.…”

“…The main feature of this interaction is very high localization of the electromagnetic field in a very small volume near the MS interface. Recently, the enhancement of light transmittance through periodically corrugated thin absorptive film under the SPP excitation condition as a function of mutual correlation of both film surfaces was theoretically considered in [15]. Here, an increased transmittance in the SPP regime explained by coupling the surface electromagnetic waves at different interfaces of metal film is calculated for SBH solar cells.…”

“…Two basic mechanisms have been proposed to explain photocurrent enhancement by metal nanoparticles incorporated into SC: light scattering and near-field concentration of light. • Relief-induced transparency enhancement due to SP excitation in rough corrugated emitter metal film [13] or SPP excitation in periodical corrugated conductive film [14][15][16].…”

The process of excitation of surface plasmon polaritons in periodically corrugated metal or heavily doped semiconductor film (emitter) in heterostructure solar cells has been investigated theoretically. This process leads to the essential increase of light transmission into the photoactive semiconductor base. As a result, the efficiency enhancement of a surface barrier heterostructure of metal-semiconductor type, η ∝ J SC • V OC , has been predicted. Besides, the internal quantum efficiency Q i (λ) has been calculated in the 1D model and the influence of both surface recombination velocity and the rate of major carriers emission into the emitter has been analyzed. The latter leads to some decrease of the open-circuit voltage V OC . However, due to the enhancement of light transmittance into the absorptive layer of the surface barrier heterostructure in the case of anticorrelated relief, the short-circuit current J SC can be increased up to twice. Therefore, the increase in the solar cell efficiency η due to excitation of surface plasmon polaritons in a corrugated front metal film has been predicted.
