Solid solutions CuIn(1-x)GaxS2 (x ≤ 0.3)were synthesized, with a yield of 70%, by reaction in molten KSCN at 400°C for 24h of CuCl2, InCl3 and GaCl3 with a ratio KSCN/Cu=15. The homogeneous solid solutions obtained are formed of nano-sized grains (70–100nm), with a specific surface area of 6.5 m2/g and a band gap between 1.5 and 1.8 eV.
