Facile synthesis of Cu2ZnSnS4 nanocrystals

CrystEngComm, 2011
A facile, greener and inexpensive method was developed to synthesize high quality quarternary Cu2ZnSnS4 (CZTS) nanocrystals at temperature lower than 220 °C, in which Cu2ZnSn(S2CNEt2)10, oleylamine and oleic acid were used as the precursor, activation agent and capping agent, respectively.

Electrodeposition of thin Cu2ZnSnS4 films

Russian Journal of Electrochemistry, 2017
The electrochemical behavior of copper(II), zinc(II), and thiosulfate (S2O3 2-) ions on the molybdenum electrode in individual 0.2 М sodium sulfate solutions (рН 6.7) and with addition of either 0.1 М tartaric acid (рН 4.6) or 0.1 М citric acid (рН 4.7) is studied.

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.

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.

Improvement of Mo/Cu2ZnSnS4 interface for Cu2ZnSnS4 (CZTS) thin film solar cell application

MRS Proceedings, 2014
ABSTRACTThe focus of this work is on back contact improvement for sputtered CZTS thin film solar cells. Three methods have been investigated including a thin Ag coating, a thin ZnO coating on the Mo back contact and rapid thermal annealing of the back contact.

Synthesis and characterization of Cu2ZnSnS4 nanoparticles

Nanomaterials and Energy, 2015
Copper zinc tin sulfide (Cu2ZnSnS4 or CZTS) is a p-type semiconducting material with high absorption coefficient (104 cm−1) and a band gap of ~1·5 eV. Most of its constituents are earth abundant and are environmentally benign. Therefore, in this work, the authors investigated structural and optical properties of CZTS nanoparticles synthesized by ...

Size control and quantum confinement in Cu2ZnSnS4 nanocrystals

Chemical Communications, 2011
Starting with metal dithiocarbamate complexes, we synthesize colloidal Cu(2)ZnSnS(4) (CZTS) nanocrystals with diameters ranging from 2 to 7 nm. Structural and Raman scattering data confirm that CZTS is obtained rather than other possible material phases. The optical absorption spectra of nanocrystals with diameters less than 3 nm show a shift to higher
