CZTS PHD THESIS

CZTS samples produced from stacked evaporated precursors allowed achieving a maximum efficiency of 3. These studies suggested a correlation between the increase of the bandgap energy and the improvement of the material quality, which was also confirmed by the performances of the final devices. The co-sputtering route was demonstrated to be a more successful strategy, assuring a fine-control of the film composition with good process reproducibility. Cu2ZnSnS4 CZTS quaternary compound has attracted much attention in the last years as new abundant, low cost and non-toxic material, with desirable properties for thin film photovoltaic PV applications. CZTS thin films were then assembled into the solar cells and their properties as absorber layer were optimized by varying both composition and thickness. Abstract Cu2ZnSnS4 CZTS quaternary compound has attracted much attention in the last years as new abundant, low cost and non-toxic material, with desirable properties for thin film photovoltaic PV applications.

Both growth processes were found to give good quality kesterite films, showing CZTS as the main phase, large grains and suitable properties for PV application, but higher homogeneity and stoichiometry control were achieved using the co-sputtering route. A detailed investigation on CZTS optical properties, microstructure, intrinsic defect density and their correlation with the material composition is presented. The precursors were deposited using two different approaches: CZTS samples produced from stacked evaporated precursors allowed achieving a maximum efficiency of 3.

A detailed investigation on CZTS optical properties, microstructure, intrinsic defect density and their correlation with the material composition cztss presented.

A strong effect of the tin content on the bandgap energy, sub-gap absorption coefficient, crystalline domain and grain size is shown and a model based on the increase of the intrinsic defect density induced by a reduced tin content is thesos.
