Abstract

As the detrimental effects of the extraction, treatment and combustion of natural resources for energy production are clearly understood, the need for renewable energy becomes more favorable with economic competition. Solar power generation is a technically viable method, although the main drawback is the cost. Traditional silicon-based single-crystal photovoltaics are too expensive to compete with non-renewable energy, while alternative materials such as cadmium telluride and copper-indium-gallium-selenide contain expensive and unstable elements, while cadmium is a carcinogen. Za is known. Copper-zinc-tin sulfide (CZTS) is another alternative, although the technology is not yet advanced enough to enter the market. The present work is a study on the synthesis of CZTS nanostructures using aerosol spray pyrolysis based on CZTS nanostructures for photovoltaic applications in an inexpensive, environmentally friendly and industrially extensible manner. We dissolve a precursor solution with air-soluble copper, zinc, and tin compounds and pass the droplets through the furnace, where the precursors dissolve to form CZTS structures thermally. Using this method, we can produce thin films - by placing a substrate inside the furnace - and nanoparticles.
