Thermally evaporated Cu2ZnSnS4 solar cells

Applied Physics Letters, 2010
High efficiency Cu2ZnSnS4 solar cells have been fabricated on glass substrates by thermal evaporation of Cu, Zn, Sn, and S. Solar cells with up to 6.8% efficiency were obtained with absorber layer thicknesses less than 1 μm and annealing times in the minutes.

Microphotoluminescence study of Cu2ZnSnS4 polycrystals

Journal of Photonics for Energy, 2013
Microphotoluminescence studies of Cu 2 ZnSnS 4 polycrystals were performed. At room temperature, two photoluminescence (PL) bands were detected at 1.39 and 1.53 eV and attributed to band-to-tail (BT) and band-to-band (BB) recombination, respectively. At lower temperatures, band-to-impurity recombination always dominates.

Sprayed films of stannite Cu2ZnSnS4

Applied Surface Science, 1996
Abstract A stoichiometric Cu2ZnSnS4 film with the stannite structure and resistivity of 2 × 10 2 Ω · cm has been prepared by annealing polycrystalline quaternary films at 550°C, which are spray-deposited on glass substrates, in an argon gas flow containing H2S.

Preparations of Cu2ZnSnS4 thin films and Cu2ZnSnS4/Si heterojunctions on silicon substrates by sputtering

Optik, 2016
Abstract The single-crystalline silicon substrate has close lattice constant with Cu 2 ZnSnS 4 (CZTS), which is beneficial to the crystalline growth of CZTS thin films. In this work, the CZTS thin films were deposited on silicon substrates by sputtering and post-sulfurization to form CZTS/Si heterojunctions.

Comparative study of Cu2ZnSnS4 film growth

Solar Energy Materials and Solar Cells, 2011
We fabricated Cu2ZnSnS4 (CZTS) thin films using two different methods, spray pyrolysis and sulfurization of Cu–Zn–Sn metallic films. Spray pyrolysis was carried out under air ambient with modified ultrasonic spray system. Sulfurizations of metallic Cu–Zn–Sn films were done for stacked metallic films, Cu/Sn/Zn/glass, Cu/Sn/Cu/Zn/glass and Sn/Cu/Zn/glass,

Cu2ZnSnS4 thin film solar cells

Thin Solid Films, 2005
Abstract Aiming to develop the solar cells free from the environmental contaminants, promising solar cell of a thin film type could be produced by using Cu 2 ZnSnS 4 (CZTS) film as the absorber. The CZTS film possesses promising characteristic optical properties; band gap energy of about 1.5 eV and large absorption coefficient in the order of 10 4 ...

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): $${{\Delta }_{f}}H_{{298.5}}^{0}$$

Aqueous synthesis of wurtzite Cu2ZnSnS4 nanocrystals

Materials Letters, 2013
Abstract Ternary and quaternary chalcogenides are thought to be promising candidates for low cost and sustainable solar energy converting devices due to large extinction coefficient and ideal band gap energy. Among them, Cu 2 ZnSnS 4 (CZTS) is one of the most important materials because of its earth-abundant as well as non-toxic elements.
