摘要：

Sol-gel-derived Cu2ZnSnS4 (CZTS) thin films for low-cost thin-film solar cells were prepared by drop-casting without sulfurization, using metal chlorides and thiourea as the precursors in the mixture solvent of deionized water and ethanol. The structure of the sintered films was kesterite phase mixed with few SnS2 nanocrystals. Many nano-rods were contained in the sintered films. The compositions of Cu:Zn:Sn:S in the resulting films and also in nanorods were 1.6:1.2:1.0:3.4, correspond to a Zn-rich and Cu poor ratio, however, some residual Cl- ions in the films. Optical absorption spectra of the resulting films show that the band gaps were around 1.56 eV. Furthermore, the device samples of the CZTS thin-film without sulfuration solar cells with the structure (Glass/ITO/TiO2 or ZnO/CdS/CZTS/Ag-electrode) were prepared. In the device samples, sol-gel TiO2 and ZnO thin-films were prepared by sol-gel solution. The typical current density-voltage (J-V) curves reveals an open circuit voltage of 267 mV, a short current density of 0.025 mA/cm2 and a fill factor of 32% for the sol-gel derived CZTS solar cells under light irradiation. © 2015, Editorial Department of Journal of the Chinese Ceramic Society.
