Analytical model for the optical functions of amorphous semiconductors and its applications for thin film solar cells

Structural, optical and hydrophilic properties of nanocrystalline TiO2 ultra-thin films prepared by pulsed dc reactive magnetron sputtering

“…With such physical model, the Cody-Lorentz oscillator was used to represent the optical dispersion model. The CodyLorentz oscillator enabled us to deduce optical band gap and exploit band-to-band transition regions between the band edge and the Urbach tail [8,[20][21][22].…”

Optimization of random diffraction gratings in thin-film solar cells using genetic algorithms

“…The amorphous silicon thickness is assumed to be 1 mm and conformal coverage is assumed for cells with periodic gratings. Material parameters used for a-Si and ZnO are taken from literature [16][17][18][19]. As a result, flat cells and cells with periodic gratings have the same amount of amorphous silicon material, and comparison of quantum efficiency reflects the lighttrapping capability of the structure.…”

Modified Tauc–Lorentz dispersion model leading to a more accurate representation of absorption features below the bandgap

“…Because of that some modifications of the original FB model have been derived by McGahan et al [27], Liu et al [28], Laidani et al [29], He et al [30]. More realistic Tauc-Lorentz (TL) and Cody-Lorentz (CL) parameterizations for the optical functions of amorphous materials have been proposed by Jellison and Modine [31][32][33] and Ferlauto et al [34,35].…”
