| Popis: | This paper focuses on field absorption by metallic nanoantennas as a means to enhance light trapping into thin-film solar cells. It determines the optimum metal nanoantennas distribution for solar cell applications. The proposed structure takes into account the interactions between the nano-particles as well as including their interaction with the absorbing substrate. Tapered structure is proposed for absorption enhancement using different metal nanoantennas like gold, silver, copper and aluminium. The sizes of nanoantennas are tapered in one direction. The tapered structures are composed of an array of metal nanoantennas and the sizes are tapered using two different ways according to the tapering direction. The degree of tapering can be set by controlling a scaling element. All simulation data are obtained using the frequency domain finite element method. Larger than 20% increase in the absorption level can be achieved using the proposed structures. |
