Spray pyrolysis of CuInS2

Spray pyrolysis is a low-cost method of depositing thin films and is econom ically more attractive than other methods that have been used to produce st able CuInS2 thin films. The electrical, optical and structural properties o f the films, as prepared, are presented together with their evolution and w ith a variation of some fabrication parameters which are the fabrication te mperature T-s, and the ionic ratio R = Cu:In:S in the solution.
