description: Th e objective of this PhD is the study of the fabrication and characterization of radial junction solar cells based on crystalline silicon nanowires. A study of the nanowire growth with two metallic catalysts (copper and aluminum) in a reduced pressure chemical vapor deposition system is presented. Th e influence of the growth conditions on the morphology, doping density and catalyst contamination inside the nanowires is analyzed by electrical, chemical (SIMS) and structural (SEM, TEM, Raman) characterizations. Copper catalyst is used to fabricate a solar cell with p-type nanowire with a radial junction created by n-type amorphous silicon (a-Si:H) deposition. Photovoltaic performances are measured and interpreted. A conversion efficiency of 5% is measured on a solar cell with 1,5 µm high silicon nanowires
