CZTS PHD THESIS

The co-sputtering route was demonstrated to be a more successful strategy, assuring a fine-control of the film composition with good process reproducibility. 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. A detailed investigation on CZTS optical properties, microstructure, intrinsic defect density and their correlation with the material composition is presented. Ateneo Biblioteca Unitn-Eprints Research. PhD thesis, University of Trento. The relationship between the absorber layer stoichiometry and the device performances was investigated:

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

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 precursors were deposited using two different approaches: A fast improvement of solar cell efficiency was obtained using this approach and a maximum efficiency of 5.

In this work, CZTS thin films were grown using two different processes, based on vacuum deposition of precursors, followed by a heat treatment in sulphur atmosphere.

  CAREER DECIDEDNESS TYPES A LITERATURE REVIEW

czts phd thesis

CZTS samples produced from stacked evaporated precursors allowed achieving a maximum efficiency of 3. Both growth processes were found to give good cxts 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.
