METHODS AND SYSTEMS FOR FORMING FUNCTIONALLY GRADED FILMS BY SPRAY PYROLYSIS

摘要

Method and system for forming a plurality of cadmium-sulfide layers. The method includes preparing a first solution and a second solution. The method further includes loading at least the first solution and the second solution into a pyrolysis-deposition system and placing a target structure into the pyrolysis-depositions system. The method further includes spraying the first solution through one or more first nozzles towards the target structure, forming, from the sprayed first solution, the first cadmium-sulfide layer, directly or indirectly, on the target structure, spraying the second solution through one or more second nozzles towards the target structure with at least the first cadmium-sulfide layer, and forming, from the sprayed second solution, the second cadmium-sulfide layer directly or indirectly, on the target structure. The first cadmium-sulfide layer includes a first cadmium-sulfide material the second cadmium-sulfide layer includes a second cadmium-sulfide material that are different in at least one material property.
