Kesterite semiconductors such as Cu2ZnSnS4, Cu2ZnSnSe4 and Cu2ZnSn(SSe)4 have received a great deal of attention from scientific community for solar cell applications since they present p-type conductivity, direct band-gap transitions, a relatively high absorption coefficient and a band-gap that can be tailored in the range of 1.0-1.5 eV as a function of Se/S compositional ratio. Besides, these materials are based on abundant and low toxicity elements. In spite of the great effort carried out by the scientific community to promote device performance, Kesterite solar cell efficiency is still limited to values lower than 13%. In this sense, new strategies are required to overcome currently reported values. In this paper, a minireview on the state of the art concerning Kesterite solar cell technology is presented. Different current trends to promote Kesterite solar cell efficiency are presented and discussed.
