Defect Properties of Na and K in Cu2ZnSnS4 from Hybrid Functional Calculation

, 2017
In-growth or post-deposition treatment of $Cu_{2}ZnSnS_{4}$ (CZTS) absorber layer had led to improved photovoltaic efficiency, however, the underlying physical mechanism of such improvements are less studied. In this study, the thermodynamics of Na and K

Synthesis of large CZTSe nanoparticles through a two-step hot-injection method [PDF]

, 2015
Grain boundaries in Cu2ZnSn(SxSe1x)4 (CZTSSe) thin films act as a defect that reduces the mobility of the charges. Hence one way to improve the performance of these thin film solar cells is to increase the grain size in the films.

The importance of back contact modification in Cu2ZnSnSe4 solar cells: The role of a thin MoO2 layer [PDF]

, 2016
Cu2ZnSn(SxSe1-x)4 (CZTSSe) photovoltaic absorbers could be the earth-abundant and low toxicity replacement for the already commercialized CuIn1-xGaxSe2 (CIGS) thin film technology.

Assessing Proton Radiation Hardness of Antimony Chalcogenide Solar Cells

Solar RRL, Volume 10, Issue 6, 29 March 2026.
This paper discusses the effect of proton radiation on the device performance of antimony chalcogenide solar cells. Sb2S3 and Sb2(S, Se)3 solar cells are exposed to two different proton energies (100 and 300 keV) with fluences ranging from 1011 to 1014 protons/cm2.

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

Band-gap engineering of Cu2ZnSn1-xGe xS4 single crystals and influence of the surface properties [PDF]

, 2016
Thin film solar cells based on Cu2ZnSn(S,Se)4 are very promising, because they contain earth-abundant elements and show high absorptivity. However, the performance of these solar cells needs to be improved in order to reach efficiencies as high as that ...

Li Incorporation Induces Surface Chemical Disorder in Solution‐Processed Cu2ZnSn(S,Se)4

Advanced Materials Interfaces, Volume 13, Issue 5, 4 March 2026.
Lithium incorporation into Cu2ZnSn(S,Se)4 (CZTSSe) thin‐film semiconductors is highly beneficial for solar power conversion efficiencies, although directly visualising its impact on the absorber is difficult. Energy‐filtered photoemission electron microscopy measurements reveal lithium alloying induces surface chemical disorder of CZTSSe, highlighted ...

Device modelling and numerical analysis of high-efficiency double absorbers solar cells with diverse transport layer materials

Results in Optics
Recently, a lot of focus has been placed on cesium lead iodide (CsPbI3) since it is considered a potentially useful inorganic halide perovskite with improved stability. Moreover, another potential absorber material is the mixed chalcogenide CZTSSe, which

Cu2ZnSn(S,Se)4 from CuxSnSy nanoparticle precursors on ZnO nanorod arrays [PDF]

, 2013
Solar cells with Cu2ZnSnS4 absorber thin films have a potential for high energy conversion efficiencies with earth-abundant and non-toxic elements. In this work the formation of CZTSSe from CuxSnSy nanoparticles (NPs) deposited on ZnO nanorod (NR) arrays
