Abstract

This project of thesis aims at developing technologies facilitating the production of passivated contact silicon solar cells and tandem (perovskite on silicon) cell structures. Both of these cells structures involve doped polycrystalline silicon nano-layers. In the case of boron doped layers, limiting factors such as layer parasitic absorption, contacting issues, and poor passivation properties when deposited on top of textured surfaces, need to be tackled. The main goal of the thesis will be the development , characterization and optimization of such a boron doped poly-Si nano-layer, either by LPCVD or PECVD deposition technique in the purpose of improving both its optical, contacting and passivating properties (700mV on textured surface is a starting target). The different technological bricks developed during the PhD will be used in PV solar devices in order to demonstrate the conversion efficiency gain and potential associated, with a target of > 25% efficient-devices. The results obtained by the PhD student will be presented in the form of scientific articles, patents and oral presentation in international conferences. The PhD student will be given the opportunity to supervise Master internships. The Thesis lasts 3 years, and will be done at the French National Solar Energy Institute (INES), on the Technolac campus, (73355 Bourget du Lac).
