This paper presents a computational study of nanostructure-enhanced solar cells. The computer model is developed based on the FDTD solution of the Maxwell equations describing the light propagation in thin film solar cells. With the model, a combination of Ag nanoparticle arrays at the top, Ag nanoparticle embedded into absorption layer and nanograting structures at the bottom of a thin film solar cell is studied. Each nanostructure is known to be capable of enhancing the solar light absorption to a certain degree, with the effect of metal particles coming primarily from the light scattering, the embedded particles from the reflection and that of back reflector from light trapping and reflection. The preliminary data from model simulation illustrate that with an appropriate combination and arrangement of these nanostructures, an increase in both short and long wavelength range can be achieved, thereby overcoming the shorting comings of each of the nanostructures when applied alone.

Broadband Absorption

The thin-film solar cell structure with a broadband absorption enhancement is reported. We designed spherical silver (Ag) nanoparticle arrays on or embedded partially into indium tin oxide (ITO) layer of the hydrogenated microcrystalline silicon ([Formula: see text]c-Si:H) thin-film solar cells. The geometrical parameters, such as nanoparticle radius ([Formula: see text], array period ([Formula: see text] and ITO layer thickness ([Formula: see text] are optimized by using the finite element method (FEM). The numerical results show that the key parameter that influences the integrated absorption is period/radius ratio ([Formula: see text]/[Formula: see text] for Ag nanoparticle arrays. Embedding nanoparticle arrays partially into ITO layer with the appropriate thickness can improve broadband light-trapping. The optimized structure shows 50.1% enhancement in the integrated absorption compared to the reference cell when [Formula: see text][Formula: see text]nm, [Formula: see text][Formula: see text]nm and [Formula: see text][Formula: see text]nm. Furthermore, physical mechanisms of absorption enhancement in different wavelength range are discussed according to the electrical field amplitude distributions in the solar cells.

Back–side diffraction gratings enhance a solar cell’s near–band–gap response by diffracting light into higher orders and thereby reducing front–side escape losses. The resulting increased photon absorption and carrier generation improves short–circuit current densities and solar cell efficiencies. Combining rigorous coupled–wave analysis and ray tracing yields a three–dimensional, polarization sensitive optical model to calculate Si absorbance, front–side and back–side losses. For industrially used, pyramidally textured, 180 μm Si solar cells with 85 nm SiNxanti–reflection coating, the application of an optimized back–side grating enhances the short–circuit current density by ≈ +1 mA/cm2, a relative increase of ≈ +2.7 %.
