Standard Enthalpy of Kesterite (Cu2ZnSnS4) Formation

Geochemistry International, 2019
Calorimetrically 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): $${{\Delta }_{f}}H_{{298.5}}^{0}$$

Kesterites—a challenging material for solar cells

Progress in Photovoltaics: Research and Applications, 2012
ABSTRACTKesterite materials (Cu2ZnSn(S,Se)4) are made from non‐toxic, earth‐abundant and low‐cost raw materials. We summarise here the structural and electronic material data relevant for the solar cells. The equilibrium structure of both Cu2ZnSnS4 and Cu2ZnSnSe4 is the kesterite structure.

Bifacial Kesterite Solar Cells on FTO Substrates

ACS Sustainable Chemistry & Engineering, 2017
The thin film kesterite-type Cu2ZnSnSe4 (CZTSe) and Cu2ZnSn(SxSe1–x)4 (CZTSSe) chalcogenides are promising materials due to their composition based on earth abundant elements and proven photovoltaic performance in solar cells. The use of transparent back electrodes for photovoltaic applications, adds to this family of thin film devices a plethora of ...

Existence of off-stoichiometric single phase kesterite

Journal of Alloys and Compounds, 2016
Abstract In this work the flexibility of the kesterite structure is discussed. It is shown that kesterite type CZTS and CZTSe can deviate from stoichiometric composition by the formation of intrinsic point defects leading to different off-stoichiometric kesterite types.

The Consequences of Kesterite Equilibria for Efficient Solar Cells

Journal of the American Chemical Society, 2011
Copper-zinc-tin-chalcogenide kesterites, Cu(2)ZnSnS(4) and Cu(2)ZnSnSe(4) (CZTS(e)) are ideal candidates for the production of thin film solar cells on large scales due to the high natural abundance of all constituents, a tunable direct band gap ranging from 1.0 to 1.5 eV, a large absorption coefficient, and demonstrated power conversion efficiencies ...
