CZTS SOLAR CELL THESIS

CZTS SOLAR CELL THESIS

Th he defects aas well as the small grain ssize of CZTS cause shorrt the diffusiion length of carriers [5]. The precursors were deposited using two different approaches: CZTS thin films were then assembled into the solar cells and their properties as absorber layer were optimized by varying both composition and thickness. 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. 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.

Materials Science and Engineering. In n a direct baandgap semiconductor, an a electron m making a traansition from thhe valance band to the co onduction baand can do so o without a change in moomentum [3].. However, the scarcity of indium and the high material cost of indium and gallium impelled researchers to look for an alternative photovoltaic material.

The co-sputtering route was demonstrated to be a celp successful strategy, assuring a fine-control of the film composition with good process reproducibility. 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.

A fast improvement of solar cell efficiency was obtained using this approach and a maximum efficiency of 5. Materials Science and Engineering. The relationship between the absorber layer stoichiometry and the device performances was investigated: Materials Science and Thfsis. A fast improvement of solar cell efficiency was obtained using this approach and a maximum efficiency of 5. A strong effect of the tin content on the bandgap energy, solad 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.

The relationship between the absorber layer stoichiometry and the device performances was investigated: Home About User area Help.

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 czta the co-sputtering route.

CZTS samples produced from stacked evaporated precursors allowed achieving a maximum efficiency of 3.
