Thermal and electrical conductivity of single crystalline kesterite Cu2ZnSnS4

Materials Research Express, 2020
For single crystalline sulfur-based kesterite Cu _2 ZnSnS _4 the electrical and thermal conductivity are measured from 20 K to 320 K. The electrical conductivity decreases exponentially with decreasing temperature.

Kesterites and Chalcopyrites: A Comparison of Close Cousins [PDF]

MRS Proceedings, 2011
ABSTRACTChalcopyrite solar cells based on CuInSe2 and associated alloys have demonstrated high efficiencies, with current annual shipments in the hundreds of megawatts (MW) range and increasing. Largely due to concern over possible indium (In) scarcity, a related set of materials, the kesterites, which comprise Cu2ZnSnS4 and associated alloys, has ...

Critical review on the controllable growth and post-annealing on the heterojunction of the kesterite solar cells

JPhys Energy
Kesterite-structured solar cells have drawn significant attention due to their low-cost and environmental friendly composition. Recently, a remarkable certified power conversion efficiency (PCE) of 14.9% has been achieved, indicating a broader prospect ...

Cation Distribution in Li2CaSiO4:Gd, Pr, Na Uncovered Through Anomalous Diffraction

European Journal of Inorganic Chemistry, Volume 29, Issue 20, 17 July 2026.
Li2CaSiO4 co‐doped with Gd3+ and Pr3+ shows strong blue‐to‐UV‐B up‐conversion. Herein, we explore the doping element distribution in order to discern the reason for the strongly supportive co‐doping effect using high‐resolution Rietveld refinement and multiple‐edge anomalous dispersion measurements.

The electrical and optical properties of kesterites

Journal of Physics: Energy, 2019
AbstractKesterite Cu2ZnSn(SxSe1-x)4(CZTSSe) semiconductor materials have been extensively studied over the past decade, however despite significant efforts, the open circuit voltage remains below 60% of the theoretical maximum. Understanding the optical and electrical properties is critical to explaining and solving the voltage deficit.

Photovoltaic response of natural Kesterite crystals [PDF]

Solar Energy Materials and Solar Cells, 2016
Abstract The photoelectrochemical performance of naturally occurring single and multicrystalline Kesterite or Cu2(Zn,Fe)SnS4 (CZTS) is presented. Elemental analyses of the crystals indicate high sulfur to metal atomic ratios and the presence of 12.3–14.5 at% of iron presumably in the 2+ metal site replacing zinc in the lattice.

When Cubic is Not Isotropic: Phonon–Exciton Decoupling in CuInSnS4 Single Crystals

Advanced Optical Materials, Volume 14, Issue 26, 10 July 2026.
A cubic CuInSnS4 crystal does not fully play by cubic rules. While phonons follow the average iso‐tropic lattice symmetry, the disorder‐localized excitons break away, showing strong, and reproduci‐ble polarization‐dependent emission. This work shows how intrinsic cation disorder can turn a mac‐roscopically cubic material into a source of hidden ...

Dynamic Impurity Redistributions in Kesterite Absorbers [PDF]

physica status solidi (b), 2020
Cu2ZnSn(S,Se)4 is a promising nontoxic earth‐abundant solar cell absorber. To optimize the thin films for solar cell device performance, postdeposition treatments at temperatures below the crystallization temperature are normally performed, which alter the surface and bulk properties.

Band Gap Tuning of Cu2ZnGeSxSe4-x Absorbers for Thin-Film Solar Cells

Energies, 2017
In this work, kesterite-type Cu2ZnGeSxSe4-x absorbers were prepared by a two-step process for use in thin-film solar cells. Their high band gap makes them an interesting candidate as top cells in multijunction solar cells. However, an exact tuning of the

Ag‐Promoted Na Retention for Synergistic Defect Passivation in Kesterite Solar Cells

Advanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
A synergistic Ag–Na codoping strategy in solution‐processed kesterite solar cells enables simultaneous lattice ordering and defect passivation. Ag promotes grain growth and Na retention, while Na enhances carrier concentration and reduces recombination.
