All the data files, except Sopra's special alloy format, were converted to the TFCalc format by Software Spectra. Company in France made its optical database available. Using the transfer matrix method and a finite element method implementation to rigorously solve Maxwell’s equations, we discuss anti-reflection and scattering properties of the different front interface designs in view of the angular distribution of incident light. The Sopra company, which manufactures ellipsometers to determine the refractive index of materials, recently posted a database containing optical data of. Optical Data from Sopra SA Contents Index Home The Sopra S.A. The compared geometries comprise multilayer coatings, gratings with step and continuous profiles as well as combinations thereof. The typically low refractive index (n 1.5 2.2) of the host materials. The index spectra collections also contain functions for MATLAB and Octave that allow the data files to be read by the TFTB thin film toolbox.
#SOPRA REFRACTIVE INDEX DATABASE ARCHIVE#
In this contribution we present a comparative simulation study of several 1D, 2D and 3D nano-optical designs for the substrate / illumination side interface to the several micrometer thick back contacted LPC silicon absorber material. The data collections in this archive combine all publicly available refractive index data I could find on the Web, with the exception of those data still buried in scientific publications. While typical multijunction photovoltaic devices have a very complicated optical structure, it is benecial to compare the designs using a simpler. All of the optical constants used for these models were obtained from the Sopra optical database 4, 5, 17, 18. Resonant coupling of the incident diffracted light with supported waveguide modes in light absorbing layer at particular wavelengths predicted by. The lateral grain size of these polycrystalline cells is in the millimeter range at an absorber thickness of up to 10 m. it has a high refractive index that is representative of many IIIV materials used in 3-J and 4-J architectures. The application of nanostructured indium-doped tin oxide (ITO) electrodes as diffraction gratings for light absorption enhancement in colloidal quantum dot solar cells is numerically investigated using finite-difference time-domain (FDTD) simulation. Rech, B.Ī new generation of polycrystalline silicon thin film solar cells is currently being developed in laboratories, employing a combination of novel laser or electron beam based liquid phase crystallization (LPC) techniques and single side contacting systems. The measurement in a spectral range cancels the. A comparison of scattering and non-scattering anti-reflection designs for back contacted polycrystalline thin film silicon solar cells in superstrate configuration A comparison of scattering and non-scattering anti-reflection designs for back contacted. It means that for a given refractive index, the thickness follows its specific and periodic ellipsometric curve.
