Physical methods are energy-intensive, requiring specialized vacuum equipment that is bulky, expensive, and demands highly skilled personnel for operation and maintenance. These factors have led to the search for alternative approaches to obtain semiconductor films. Non-vacuum chemical methods allow for the deposition of films of various compounds at atmospheric pressure, offering economic efficiency, accessibility, and lower energy consumption compared to vacuum-based techniques. These methods are easily scalable, enable the production of large-area films with controlled characteristics on flexible substrates, and impose fewer requirements on equipment. In fact, a technological shift is currently underway, moving from the use of physical methods for depositing semiconductor materials to chemical methods. The project initiates the development of breakthrough technology for manufacturing sensitive electronic elements based on oxide (CuO, ZnO, NiO), sulfide (SnS), and kesterite (CZTSSe) semiconductor materials using 2D and 3D printers, which belong to the technologies of the Fourth Industrial (Technological) Revolution. The proposed chemical printing technology utilizing nanoparticle inks is energy-efficient, environmentally friendly, easily scalable, and can be operated by low-skilled personnel under specific conditions. It is worth noting that all compounds studied in this work are environmentally safe and consist of elements that are abundantly available in the Earth's crust Product Description popup.authors Yevdokymenko Vladyslav Yu.
