Tsoulka, Polyxeni. "Local inhomogeneities in polycrystalline wide band gap Culn1-xGaxSe2 thin-films". Thesis, Nantes, 2019. http://www.theses.fr/2019NANT4009/document.
Texto completo da fonteAmongst the different semiconductor materials used as absorber layers, polycrystalline CuIn1-xGaxSe2 is one of the most promising materials in the thin-film photovoltaic technology. Due to the high efficiency, stability and band gap tunability with x, thin-film solar cells based on CuIn1-xGaxSe2 absorber layer are already industrially implemented. Moreover, in the multi-junction solar cell technology the aim of reaching higher efficiencies while keeping the fabrication costs low, makes the wide band gap indium-free CuGaSe2 absorber layer an interesting candidate as a top cell in a hybrid tandem solar cell based on c-Si bottom cell. However, the actual energy conversion efficiency strongly decreases for x larger than 0.3 and it does not follow the theoretical predictions indicating better performances for x around 0.7. The difficulty to obtain a high device performance for large x has been a worldwide question for several years and many theories have been proposed to explain the limited conversion efficiency. A possible cause of the limited CuIn1-xGaxSe2 performance for large x involves the local inhomogeneities at the inter- or intra-grain regions, since the nature of the accumulated species or compound at the interfaces can be detrimental or beneficial for the solar cell efficiency. In this thesis we investigate two possible phenomena that are likely to occur at the CIGSe interfaces i) a preferential elemental segregation at the grain boundaries and ii) the detrimental copper selenide surface segregation or bulk precipitation. In this work, the elemental segregation is investigated at equilibrium by coupling ab initio calculations and thermodynamic modeling. Our results indicate that substitutional (InGa or GaIn antisite) cannot be expected in the most frequently present interfaces such as the twin grain boundaries. A complementary and simple analysis of the main segregation driving forces was also studied in order to understand the segregation in the more general cases, such as the surface segregation. Our calculations show that In is slightly more favorable to segregate at the surface rather than Ga. The experimental analysis on CuIn1-xGaxSe2 films at intermediate and large x reveals that increasing x the Cu content in the CuIn1-xGaxSe2 film can locally differ, creating detrimental Cu-enriched domains within the bulk of the film. This phenomenon is due to the slow kinetics at large x and the reduced Cu and Ga interdiffusion. In this work, we propose a strategy to avoid these local inhomogeneities by applying a relaxation stage during the CuIn1-xGaxSe2 deposition process. This stage improves the photovoltaic performance, since it leads to a long-range equilibration, grain growth, annihilation of voids and a close to stoichiometry bulk which was expected

A Potential Seebeck Microprobe apparatus is described that a profile of Seebeck coefficients can be detected on a material sample surface for thermopower investigations. Due to its spatially resolved limit on detecting small inhomogeneities of dopants or composition changes, we here propose a constructive combination of ANSYS coupled-field numerical simulation and digital signal processing in order to improve the spatial resolution by deconvolution algorithm. The relevant transfer function, obtained from numerical calculations, was validated and successfully applied to theoretical and experimental data. The improvement in detecting thermoelectric bulk material sample was demonstrated, in which the spatial resolution of Potential Seebeck Microprobe is increased by the inverse of measured Seebeck signal. Also, the systemic preconditions (tip size, signal capture time and scan period), which are the main factors to affect the captured thermovoltages, were discussed in detail. In addition, for detecting thermoelectric film material sample, we found that the heat flow penetrating into substrate causes an additional Seebeck distortion, leading to a low spatial resolution. Therefore, a correct transfer function, according to the characteristic of Potential Seebeck Microprobe as a low-pass filter, is next proposed for the successful spatial resolution improvement. Finally, we provide an efficient route to use model order reduction, which reduces the transient three-dimensional analysis time, for searching the required transfer functions. Thus, we can fast perform significant improvements beyond the current measured resolution of Potential Seebeck Microprobe, which is the unique technique to detect the thermopower of thermoelectric inhomogeneities.
