Abstract Presented is a study on the mechanochemically assisted synthesis of kesterite Cu2ZnSnS4 from the elements for photovoltaic applications. Initial application of high energy ball milling under selected conditions, including the highest achievable rotation speeds up to 1000 rpm, affords a pure cubic nanophase with the nominal kesterite ...

High-field hopping magnetotransport in kesterites
Journal of Magnetism and Magnetic Materials, 2018Abstract Transport properties of the kesterite-like single crystals of Cu2ZnSnS4, Cu2ZnSnxGe1−xSe4 and Cu2ZnGeS4 are investigated in pulsed magnetic fields up to B = 20 T. The Mott variable-range hopping (VRH) conduction is established by investigations of the resistivity, ρ (T), in all the materials mentioned above within broad temperature intervals

Laser operation by kesterite chalcogenide nanocrystals
Optik, 2019Abstract We demonstrate a possibility to vary structural, morphological and optoelectronics parameters for kesterite Cu2ZnSnS4 nanocrystalline films using external laser beams at 1540 nm, and 770 nm or 1064 nm, and 532 nm. The illumination is performed both by single mode laser beams as well as by bicolor coherent treatment.

Determination of tin as stannite-kesterite and cassiterite in ores
Talanta, 1975Tin is stannite-kesterite and as cassiterite in a tin-bearing ore can be determined by the selective decomposition of the stannite-kesterite phase with a mixture of sodium nitrate and acetic acid.

Growth kinetics during kesterite coevaporation
2012 38th IEEE Photovoltaic Specialists Conference, 2012Kesterite solar cells have been considered as earth-abundant substitute to chalcopyrites. NREL's 9.2% co-evaporated kesterite solar cell is inspired by the copper-rich growth of co-evaporated chalcopyrites. The excess Cu x Se y is believed to conduct liquid-phase assisted grain growth and hence improves the device performance.

Standard Enthalpy of Kesterite (Cu2ZnSnS4) Formation
Geochemistry International, 2019Calorimetrically determined enthalpy of kesterite (Cu2ZnSnS4) formation from simple sulfides 2CuS + ZnS + SnS → Cu2ZnSnS4 was utilized to calculate the standard enthalpy of formation of Cu2ZnSnS4 (from elements at a pressure of 105 Pa): $${{\Delta }_{f}}H_{{298.5}}^{0}$$
