“…The selection of the physical parameters of the Zn 1Àx Ge x O (ZGO) buffer layer represents the most critical aspect of our model. Indeed, experimental data is only available for the ternary compound Zn 2 GeO 4 and very few papers focus on other Zn/Ge ratios [41][42][43][44]. In order to simulate the solar cell structure, an estimation of the bandgap energy E g , of the electron affinity x and of the permittivity e r are done through a linear interpolation over the whole composition range between the physical parameters of zinc oxide and germanium oxide using the following equations:…”

Numerical simulations of AZO/Zn1−xGexO/Cu2O solar cell are performed in order to model for the first time the impact of the germanium composition of the ZnGeO buffer layer on the photovoltaic conversion efficiency. The physical parameters of the model are chosen with special care to match literature experimental measurements or are interpolated using the values from binary metal oxides in the case of the new Zn1−xGexO compound. The solar cell model accuracy is then confirmed thanks to the comparison of its predictions with measurements from the literature that were done on experimental devices obtained by thermal oxidation. This validation of the AZO/Zn1−xGexO/Cu2O model then allows to study the impact of the use of the low cost, environmental friendly and industrially compatible spray pyrolysis process on the solar cell efficiency. To that aim, the Cu2O absorber layer parameters are adjusted to typical values obtained by the spray pyrolysis process by selecting state of the art experimental data. The analysis of the impact of the absorber layer thickness, the carrier mobility, the defect and doping concentration on the solar cell performances allows to draw guidelines for ZnGeO/Cu2O thin film photovoltaic device realization through spray pyrolysis.

“…Due to the optical and electrical applications, usually, the substrates were glass and PET. The effect of Ge doping on the structural, morphological and optical properties of ZnO:Ge films was studied in [184]. The average crystallite size in the 60-80 nm thick films varied between 11 nm and 30 nm for both substrates; film roughness was greater on PET substrate.…”

Thermionic Vacuum Arc—A Versatile Technology for Thin Film Deposition and Its Applications

et al. 2020

This review summarizes the more-than-25-years of development of the so-called thermionic vacuum arc (TVA). TVA is an anodic arc discharge in vapors of the material to be deposited; the energy for its melting is delivered by means of a focused electron beam. The resulting material ions fall at the substrate where they form a well-adhesive layer; the ion energy is controllable. The deposited layers are, as a rule, free from droplets typical for cathodic arc deposition systems and the thermal stress of the substrates being coated is low. TVA is especially suitable for processing refractory metals, e.g., carbon or tungsten, however, in the course of time, various useful applications of this system originated. They include layers for fusion application, hard coatings, low-friction coatings, biomedical-applicable films, materials for optoelectronics, and for solid-state batteries. Apart from the diagnostic of the film properties, also the diagnostic of the TVA discharge itself as well as of the by TVA generated plasma was performed. The research and application of the TVA proceeds in broad international collaboration. At present, the TVA technology has found its firm place among the different procedures for thin film deposition.
