Synthesis of Cu2ZnSnS4 nanocrystals by solvothermal method

Thin Solid Films, 2013
Abstract A high-yield synthesis route to obtain phase-pure, highly crystalline Cu 2 ZnSnS 4 (CZTS) nanocrystals with controlled Cu/(Zn + Sn) ratio is reported. The material properties were investigated to understand the effect of initial precursor concentrations on the stoichiometry of CZTS nanocrystals.

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.

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.

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,

Transmittance Spectra of Cu2ZnSnS4 Thin Films

Journal of Electronic Materials, 2015
Thin films of the quaternary compound semiconductor Cu2ZnSnS4 (CZTS) were produced by ion beam sputtering at substrate temperatures of 323 K, 423 K, and 573 K. The chemical and structural properties of the thin films were studied by electron microprobe analysis and grazing incidence x-ray diffraction.

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 ...

Thermal transport in Cu2ZnSnS4 thin films

Journal of Applied Physics, 2016
The stability of kesterite Cu2ZnSnS4 (CZTS) under a range of compositions leads to the formation of a number of stable defects that appear to be necessary for high efficiency photovoltaic applications. In this work, the impact of the presence of these defects on the thermal conductivity of CZTS thin films has been explored.

Cu2ZnSnS4, Cu2ZnSnSe4, and Related Materials

2015
Kesterite-structured quaternary compounds Cu2ZnSnS4 (CZTS) and Cu2ZnSnSe4 (CZTSe) semiconductors are drawing intensive attention as the light-absorbing materials in thin-film solar cells. Because all their component elements are earth-abundant and environment-friendly, their band gaps are close to the optimal band gap of the light-absorber ...

Synthesis of Cu2ZnSnS4 nanoparticles by solvothermal route

AIP Conference Proceedings, 2016
CZTS nanoparticles of size ~ 20 nm have been synthesized by solvothermal method. X-ray diffraction pattern confirms the growth of single phase CZTS nanoparticles with kesterite structure and lattice parameter obtained as a = b = 0.54 nm and c = 1.08 nm. The Raman peak observed at 338 cm−1 also confirms the formation of pure CZTS phase.
