A new method with descending crucible has been suggested for synthesizing and growing a high quality AgGaS_2 crystal in one ampoule. A crack-free AgGaS_2 single crystal with 10mm in diameter and 20mm in length was grown by the technique above mentioned. The results show that the as-grown AgGaS_2 crystal can be used in the device research by measured EDAX spectrum, infrared transmission spectrum and XRD spectra.
