Abstract
Cu 2ZnSn(Se 1− x S x ) 4 monograin powders with different x values were prepared from binary compounds in the liquid phase of flux material (KI) in evacuated quartz ampoules at 1000 K. Narrow granulometric fractions of the grown powders were used as absorber materials in monograin layer solar cells: graphite/Cu 2ZnSn(Se 1− x S x ) 4/CdS/ZnO. The values of V oc increased with increase in content of sulfur in the absorber from 283 mV for x=0–660 mV for x=0.85.
