Paper Title:
Solvothermal Synthesis and Characterization of Quaternary Cu2ZnSnSe4 Nanocrystals
  Abstract

Quaternary compounds Cu2ZnSnSe4 is a promising candidates for low cost thin film solar cell with an optimal direct band-gap (0.85~1.65eV)and a high absorption coefficient (>104cm-1). In our study, we have been successfully synthesized Cu2ZnSnSe4 nanocrystals in ethylenediamine solution through solvothermal method using CuCl, ZnCl2, SnCl4•5H2O and Se powers as reaction reagents.The result demonstrated that Cu2ZnSnSe4 nanocrystals slightly polydispersed with most of the size of nanocrystals falling in the range 8-12 nm. Raman spectra of Cu2ZnSnSe4 nanocrystals have a redshifts as the smaller size effect. Photoluminescence spectra of Cu2ZnSnSe4 nanocrystals showed that one wide emission band with peak position around 1.40eV.
