Photonic quasicrystal nanopatterned silicon thin film for photovoltaic applications

چکیده
In this letter, the authors numerically studied the optical properties of silicon photonic quasicrystal (PQC) nanohole array for photovoltaic applications. With the same active layer thickness, the ultimate efficiency of a solar cell integrated with an optimized PQC nanohole array can be enhanced by 9.01% and 1.40% as compared to that with an ordered square lattice of nanohole array and a random nanohole array respectively. The absorptance enhancement is mainly due to the higher-order rotational symmetry in PQC structures, which leads to the presence of additional resonant modes, broadening of existing modes, and reduction of surface reflectance. The angular response for both transverse-electric and transverse-magnetic modes are also analyzed in details.

Photonic Systems for Crystalline Silicon and Thin-Film Photovoltaic Manufacturing
In this chapter, we will discuss the impact that photonics have on photovoltaic (PV) manufacturing. The broad field of photonics is now commonly thought to encompass classical optics (Hecht, 2001), nanophotonics (Joannopoulos et al., 2007), and metamaterials (Cai and Shalaev, 2009). Over the last few decades, photonic technology has become an increasingly integral part of PV manufacturing, both...
متن کاملImproving thin-film crystalline silicon solar cell efficiencies with photonic crystals.
Most photovoltaic (solar) cells are made from crystalline silicon (c-Si), which has an indirect band gap. This gives rise to weak absorption of one-third of usable solar photons. Therefore, improved light trapping schemes are needed, particularly for c-Si thin film solar cells. Here, a photonic crystal-based light-trapping approach is analyzed and compared to previous approaches. For a solar ce...
