Cellules solaires à haute tension de fonctionnement à base de Silicium ultra mince nanostructuré

Abstract : Current technologies see an exponential increase in the number of connected objects. These objects are integrated in every domain and come along with an important challenge: their energy supply. In this thesis, we propose a new Silicon solar cell architecture that is easy to integrate in a chip design. This solar cell is composed of several subcells connected in series by vertical tunnel junctions. We study the tunnel junction from an analytical point of view and develop two new models on the I(V) characteristic. Then, we develop a new process flow to fabricate auto-aligned vertical tunnel junctions. With this process flow, a first prototype shows 200 mV output voltage for an 18 µm wide cell. We could also demonstrate the impact of series connection on cells containing up to 10 tunnel junctions. Several optimisations solutions have been proposed and investigated, notably on the resistance sources. This thesis studies physical phenomena interacting in a vertical tunnel junction solar cell from an analytical point of view, with optical, physical and electrical simulations along with experiments.
