Although Cu2ZnSn (S, Se) 4 (CZTSSe) has attracted attention as an alternative to
CuInGaSe2 (CIGS) as an absorber material in solar cells, its low efficiency is a serious …

The efficiency of kesterite-based solar cells is limited by various non-ideal recombination
paths, amongst others by a high density of defect states and by the presence of binary or …

Abstract Kesterites, Cu2ZnSn (SxSe1− x) 4 (CZTSSe), solar cells suffer from severe open‐
circuit voltage (VOC) loss due to the numerous secondary phases and defects. The …

Abstract Ternary (I–III–VI) and quaternary (I–II–IV–VI) metal-chalcogenides like CuInS 2 or
Cu 2 ZnSn (S, Se) 4 are among the materials currently most intensively investigated for …

This work presents a complete analysis of Raman active modes of Sb 2 Se 3 measured by
six different excitation wavelengths from NIR to UV, under different polarization …

Robust evidences are presented showing that the Raman mode around 250 cm− 1 in the
Sb2Se3 thin films does not belong to this binary compound. The laser power density …

Cu–Zn cation disorder plays a vital and controversial role in kesterite CuZnSn (S1–x Se x) 4
solar cells. We demonstrate using density functional theory and nonadiabatic molecular …

This work presents the development of a novel chalcogenization process for the fabrication
of Cu2ZnSn (S, Se) 4 (CZTSSe or kesterite)-based solar cells that enable the generation of …

Accurate anionic control during the formation of chalcogenide solid solutions is fundamental
for tuning the physicochemical properties of this class of materials. Compositional grading is …

Fabrication on transparent soda-lime glass/fluorine-doped tin oxide (FTO) substrates opens
the way to advanced applications for kesterite solar cells such as semitransparent, bifacial …
