“…The main purpose to applying those plasmonic structures is to increase the traveling path length of photons within an SC active layer. Thus, Polo et al [38] combined SCs with so-called "nano-engineered metamaterials" [39], i.e., sculptured thin films (STFs) in a dielectric medium, to support multiple plasmonic modes in thin-film SC, thereby, rising the SC's transferring efficiency. Figure 6(a) shows the Kretschmann configuration for such a measurement setup.…”

Abstract:Silicon-based solar cells (SCs) promise to be an alternative energy source mainly due to: (1) a high efficiency-to-cost ratio, (2) the absence of environmentaldegradation issues, and (3) great reliability. Transition from wafer-based to thin-film SC significantly reduces the cost of SCs, including the cost from the material itself and the fabrication process. However, as the thickness of the absorption (or the active) layer decreases, the energy-conversion efficiency drops dramatically. As a consequence, we discuss here three techniques to increase the efficiency of silicon-based SCs: (1) photonic crystal (PC) optical couplers and (2) plasmonic optical couplers to increase efficiency of light absorption in the SCs, and (3) a radial p-n junction structure, decomposing light absorption and diffusion path into two orthogonal directions. The detailed mechanisms and recent research progress regarding these techniques are discussed in this review article.
