The pseudo dielectric function of CuZnSn(SSe) [x = 0.35, 0.62, 0.81] bulk polycrystals is determined over the range 1.1–4.6 eV at room temperature from the analysis of spectroscopic ellipsometry data using the Adachi model. From the analysis, the lowest E transition and high energy E and E transitions are clearly identified, and used to follow the evolution of the pseudo dielectric function as a function of the composition. It is shown that the fundamental E and high energy E transitions can be tuned by increasing the sulfur content over a range of 0.3 eV. These results show the potential of the kesterite compounds for the design of efficient tailored photovoltaic solar cells. The research leading to the presented results was partially supported by the European Project INFINITE-CELL (Ref. H2020-MSCA-RISE-2017-777968, 2017e2021,www.infinitecell.eu) andthe Spanish MINECO Projects“WINCOST”(ENE2016-80788-C5-2-R) and“SENSIL”RTI2018-096498-B-I00 (MCIU/AEI/FEDER, UE).The authors from the Institute of Applied Physics appreciate the financial support from the Bilateral Project No. ANCD19.80013.16.02.01F/BL and from the Institutional Project No. CSSDT15.817.02.04A.
