摘要：
Cu2ZnSn(SxSe1-x)(4) nanoparticles were synthesized by a facile solvothermal method. X-ray diffraction and Raman spectra measurements confirmed the structural transitions and phase purities of Cu2ZnSn(SxSe1-x)(4) nanoparticles. The compositional ratios of Cu2ZnSn(SxSe1-x)(4) nanoparticles were determined by energy dispersive spectrometer. With increasing Se content, more sheet-like particles appeared in the products. Absorption spectra results indicated that the bandgaps of Cu2ZnSn(SxSe1-x)(4) nanoparticles were adjustable between 0.92 and 1.5 eV. Cu2ZnSn(SxSe1-x)(4) nanoparticle-sensitized solar cells were fabricated and current density-voltage measurements displayed that sheet-like particles were contributive to the electron transmission.
