Abstract

Kesterite thin film solar cell has been fabricated by chemical spray pyrolysis (CSP) of an aqueous solution followed by high temperature selenization. The pyrolysis formation of Cu₂ZnSnS₄ was conducted in atmospheric condition with substrate temperature of 280 C. X-ray diffraction and Raman spectroscopy study confirmed the formation of the single phase Cu₂ZnSn(S,Se)₄ kesterite structure after selenization without traceable secondary phases. FESEM image shows a uniform absorber layer without carbon layer formed between CZTSSe and Mo. Power conversion efficiency of 5.1% was obtained with different amounts of selenium incorporation. Power dependent and temperature dependent photoluminescence (PL) study revealed donor-to-acceptor pairs (DAP) transition at low temperature. Severe PL quenching at temperatures above 41 K is attributed to the opening of non-radiative recombination channels from the defects associated with non-stoichiometric elemental ratio. Therefore, further enhancement of power conversion efficiency can be achieved by better control of stoichiometry.
