Study of Variation of Zn:Sn in Organically Synthesized Chalcopyrites of CZTSe
2013Liquid processed, single-phase, highly crystalline quaternary alloy of CZTSe comprising of earth-abundant and non-toxic elements Zn & Sn can be synthesized by using non-vacuum hot-injection method through careful tuning of the precursor ratios of Zn & Sn without resorting to post-synthesis selenization or high temperature methods.

Junction formation and interface effects in CZTSe solar cells
2014 IEEE 40th Photovoltaic Specialist Conference (PVSC), 2014The space charge distribution across the CZTSe/CdS heterojunction plays an important role in defining the recombination properties of Kesterite solar cells. We have conducted a study designed to manipulate the shape of the space charge region and trigger changes in the magnitude of interface recombination present in our devices.

The impact of sodium on the sub-bandgap states in CZTSe and CZTS
Applied Physics Letters, 2015We compare the optically active sub-bandgap states in polycrystalline Cu2ZnSnSe4 (CZTSe) and Cu2ZnSnS4 (CZTS) thin films as a function of sodium content. In all samples studied, we find that CZTSe has a lower concentration of radiative defect-derived states compared to CZTS and that the states are also shallower in CZTSe compared to CZTS.

Improving device performance of sputtered CZTSe based solar cells by Manganese doping [PDF]
Optical MaterialsDespite many efforts, Cu2ZnSnSe4 (CZTSe) based solar cells have remained relatively low efficiency compared to other thin film-based devices. One of the prevalent strategies used to improve cell performance in CZTSe is cation substitution.

Detection of a MoSe2 secondary phase layer in CZTSe by spectroscopic ellipsometry
Journal of Applied Physics, 2015We demonstrate the application of Spectroscopic Ellipsometry (SE) for identification of secondary phase MoSe2 in polycrystalline Cu2ZnSnSe4 (CZTSe) samples. A MoSe2 reference sample was analyzed, and its optical constants (ε1 and ε2) were extracted by SE analysis.

Resilient and reproducible processing for CZTSe solar cells in the range of 10%
Progress in Photovoltaics: Research and Applications, 2018AbstractIn this paper, we present our route to fabricate Cu2ZnSnSe4 (CZTSe) thin films, which allows to achieve reproducible processing of kesterite absorber, that leads to efficiencies in the range of 10%. The article mainly focuses on the annealing process and demonstrates that controlling of the reactor pressure for selenization can be reliably used
